CHEMICAL HYGIENE PLAN

College of Science and Technology

Central Michigan University

I           INTRODUCTION

The purpose of this Chemical Hygiene Plan (CHP) is to offer guidance on maintaining a strong chemical safety program at Central Michigan University (CMU).  This plan will ensure adequate control methods are implemented to prevent unacceptable exposure to hazardous chemicals in laboratories.  This plan has been developed to comply with the U.S. Occupational Safety and Health Administration (OSHA) Laboratory Standard (29 CFR 1910.1450) and the Michigan Department of Consumer and Industry Services Hazardous Work in Laboratories Standard (R325.70101-325.70114/Part 431).  A copy of each of these Standards can be found in Appendix H.  The intention of this plan is to serve as an employee reference for safe work practices in the laboratory.

A CHP is required in any laboratory area where hazardous materials are used or stored; however, the Standards apply only to areas where hazardous materials are used and when all the following criteria are met:

1.      chemical operations are carried out on a laboratory scale, i.e. the containers used in the operation are of a size that can be easily and safely manipulated by one person;

2.      multiple chemical procedures or chemicals are used;

3.      the procedures involved are not part of a production process nor simulate a production process; and

4.      “protective laboratory practices and equipment” are available and commonly used to prevent employee exposure.

Hazardous substances are classically defined as those materials that are either flammable, corrosive, water or air sensitive, oxidizing, explosive, or toxic.  In the Standard, a hazardous chemical is defined as a “chemical for which there is statistically significant evidence based on at least one scientific study . . . showing that acute or chronic health effects may occur in exposed employees.”  Therefore, in the College of Science and Technology, any lab, studio or shop area, in which hazardous chemicals are used, is classified as a laboratory.

In addition to faculty, staff and student employees (including graduate teaching assistants and research assistants) who spend time in the laboratory, this plan applies to all clerical, custodial, maintenance and contract personnel who, as part of their assigned duties, spend working time within the laboratory environment.  The primary emphasis of this plan is to protect laboratory workers from overexposure to hazardous substances by appropriate administrative procedures or engineering controls.

The CHP will be updated annually by the Safety Coordinator with review by the Science and Technology Safety Committee.  The CHP can be found at the following locations on campus:

IV        GENERAL SAFETY RULES

1.      Avoid working alone.  Working alone in a chemical storage area or in an area where hazardous materials are used is never a good idea and should be avoided if possible.  If the employee and supervisor of the laboratory determine that work must be done under these conditions, the hazards should be carefully assessed, contingencies thought out, and the work approved only if the chances of injury are minimal.  An effort should be made to keep in contact with the employee who is working alone.

2.      Wear the appropriate eye protection when in an area where hazardous materials are used or stored or hazardous operations are underway.

3.      When working with flammable chemicals, be certain that there are no sources of ignition near enough to cause a fire or explosion in the event of a vapor release or liquid spill.

4.      Use a tip-resistant shield for protection whenever there is the potential that an explosion or implosion might occur.

5.      When working with chemicals, be aware of:

·        The hazards of the chemicals, as determined from the MSDS or other appropriate documented references

·        Appropriate safeguards that need to be taken when using the chemical, including personal protective equipment

·        The location and proper use of all emergency equipment

·        How and where to properly store the chemical when not in use, as well as how to properly dispose of the chemical once the task is complete

·        The proper methods of transporting chemicals within the facility

·        Appropriate procedures for emergencies, including evacuation routes, spill cleanup procedures and proper waste disposal methods

6.      Do not ride in the elevator with containers of cryogenic fluids.

7.      Promptly notify the appropriate personnel in the event of an accident, injury or chemical release.

8.      Do not participate in horseplay, practical jokes or any behavior that may startle, distract or disorient another worker in an area where hazardous materials are used or where potentially dangerous operations are in place.

9.      Be alert to any unsafe condition.  If an unsafe condition exists, either remediate the problem or notify the appropriate supervisor to ensure the unsafe condition is corrected.

10.  Do not block access to emergency equipment, safety showers, eyewashes, fire extinguishers, or exits, even with temporary equipment or parked carts.

11.  Label all containers of chemicals with the full chemical name, the hazard warnings, and the concentration.

12.  Keep all work areas, workbenches, and hoods free of clutter.

13.  Keep all aisles, hallways, and stairways clear of all obstructions.

14.  Return all chemicals to their assigned storage areas at the end of each day.  Return flammable materials to flammable storage cabinets.

15.  Label and store waste containers properly.

16.  Clean all working surfaces and floors regularly.  Keep floors free of all slip and trip hazards.

17.  Do not store chemicals in hallways or stairwells, in aisles or on the floor, or on desktops or workbenches.  Return materials requiring long-term storage to the appropriate storage area.

18.  Make sure that all chemical containers are closed when not in use.

19.  Make sure that fume hoods are working properly before working with chemicals inside of them.

20.  Maintain a chemical inventory for each laboratory and indicate the location of MSDS.

21.  Dispose of glass, sharps, and waste according to section VIII of the chemical hygiene plan.

22.  Secure compressed gas cylinders at all times.  Keep cylinder caps in place when cylinders are not in use.

23.  Make sure that service/maintenance workers and visitors are not exposed to hazardous materials when they are in the lab.

24.  Prohibit children in laboratories unless an employee accompanies them from that specific laboratory area.

25.  DO NOT HAVE FOOD OR BEVERAGES IN A LABORATORY WHERE HAZARDOUS MATERIALS ARE PRESENT!!!  Food and beverages are only allowed in the hallways, office areas, and conference rooms.

26.  Wear appropriate clothing in the laboratory and animal rooms.  Shorts, short skirts, halter tops, high heels, sandals, open-toed shoes, and shoes with uppers constructed of woven material are not allowed.  Tie back long hair and loose clothing and remove dangling jewelry prior to working in the laboratory.

 V         UNDERSTANDING AND RECOGNIZING CHEMICAL HAZARDS

To ensure that employees of Central Michigan University (CMU) are not overexposed to chemicals, each employee must be knowledgeable of the chemical hazards in his/her work environment.  Each employee must be able to identify chemical hazards and understand what measures can be taken to eliminate chemical hazards.  This section addresses how to understand and recognize chemical hazards.

A.  Employee Training

The primary way to ensure that employees understand and recognize chemical hazards is through training.  Central Michigan University will provide training to its employees (graduate students, faculty, staff, graduate teaching assistants, research assistants, maintenance personnel, custodians) who work in areas where hazardous materials are used or stored and to its employees (office staff) who work in areas where hazardous materials are not used or stored yet have the potential for incidental exposure because they are located in the same building.  New employees must receive training on the requirements of the CHP prior to working with chemicals in the laboratory.  Refresher training will be provided when procedures are updated in the CHP.  Employee training records will be on file at the following two locations:

1.      236 ET Building – Safety Coordinator, College of Science and Technology

2.      103 Smith Hall – Safety Coordinator, Environmental and Safety Services

All training will include the following:

1.      The content and requirements of the Laboratory Standard.

2.      The content, location, and availability of the chemical hygiene plan.

3.      The PELs, action levels, and other recommended exposure limits for hazardous chemicals used in CMU’s laboratories.

4.      Signs and symptoms associated with exposures to the hazardous chemicals used in the laboratory.

5.      The location and availability of MSDS and other reference materials.

6.      The methods and observations that may be used to detect the presence or release of a hazardous chemical.

7.      The hazards associated with the chemicals used in CMU’s laboratories.

8.      The measures employees can use to protect themselves from these hazards, including specific procedures such as appropriate work practices, personal protective equipment to be used, and emergency procedures.

If there are any questions about CHP training (to whom does it apply, training dates and times, etc.), contact the principal investigator, the supervisor, or the safety coordinator.

B.  Identification of Hazardous Chemicals

Before starting any procedure that requires the use of a chemical, you must identify the hazards associated with the chemical.  Reading and understanding the warning or hazard labels on the chemical containers and the Material Safety Data Sheet (MSDS) for each of the chemicals used can help achieve this.  Other references available through the Safety Coordinator (including Internet sites) are listed in Appendix A.  See Section VII for more detail on the different classifications of hazardous chemicals.

C.  Signs

At a minimum, you should post the following signs in each laboratory:

1.      A listing of telephone numbers for CMU Police, safety coordinator, and supervisory personnel on the outside of the lab door.

2.      Location signs for safety equipment, such as safety showers, eye wash stations, fire extinguishers, emergency cut-off switches, and first aid equipment.

3.      Signs designating the location of MSDS information.

4.      Signs designating the areas where food and beverages are NOT permitted.

5.      Warning signs where dangerous equipment is in use or where potentially dangerous operations are taking place.

D.  Chemical Labeling

At a minimum, each new chemical container must be labeled with the following:

1.      Name of chemical (no abbreviations).

2.      Hazard warnings.

3.      Name and address of supplier.

4.   Chemical concentration.

At a minimum, you must label each transfer chemical container with the following:

1.      Name of chemical (no abbreviations).

2.      Hazard warnings.

3.   Chemical concentration.

You must also properly label containers of non-hazardous materials.  (Example:  distilled water).  Dispose of unlabeled containers as unknown hazardous waste.

E.  Material Safety Data Sheet (MSDS)

Departments shall maintain copies of Material Safety Data Sheets (MSDS) for each hazardous chemical used in their department.  MSDS must be readily accessible during each work shift to employees in their work area.  MSDS must be maintained for thirty years because they serve as exposure records.  When a new MSDS arrives, date it.  When the chemical is no longer in use or an updated MSDS is on file, forward the old MSDS copy to the Safety Coordinator.

F.  Chemical Inventory

Each department shall maintain a hazardous chemical inventory.  Update the inventory at least annually and forward a copy upon request to the Safety Coordinator (236 ET Building) for regulatory reporting.  An example template can be found in Appendix J.

Store all chemicals safely and properly.  Store by chemical classification and hazard, and separate incompatible materials.  Do not store chemicals alphabetically.  See Appendix A for references.

G.  Inspections

Principal Investigators/Supervisors are responsible for conducting periodic inspections of laboratories.  Quarterly inspections are strongly recommended.  A sample laboratory inspection checklist can be found in Appendix B.  Include personal protective equipment (PPE), safety equipment, electrical cords, laboratory equipment, and general laboratory conditions during the inspection.  If you discover any defective equipment during the safety inspection, tag it, take it out of service, and have it repaired.  If the equipment is not going to be repaired, then it is recommended that the item is either disposed of or removed to a storage location.  Maintain a file of inspection checklists and logs.

The Safety Coordinator will be responsible for inspecting/flushing safety showers and plumbed eyewash stations.  Any safety shower or eyewash not passing the inspection will be immediately tagged and taken out of service until it is repaired.  The Departments will be responsible for inspecting non-plumbed eyewash stations according to the manufacturer’s specifications.

Facilities Management will be responsible for inspecting the performance of chemical fume hoods biannually.  If any hood does not pass the inspection, it will be immediately tagged and taken out of service until it is repaired.

Facilities Management will be responsible for inspecting fire extinguishers monthly.

H.  Hazard Notification Forms for Repair Work

Follow the Lab Maintenance Safety Procedures, which can be found in Appendix C, when making a work request of Facilities Management to do work in an area where hazardous materials are used.  In summary, the procedure is as follows:

1.      Call the FM Service Center at 6547 and make your work request. 

2.      Inform the person that you will be faxing a hazard notification form to accompany the work request.

3.      Fill out the hazard notification form as the listed tasks are completed.  Tasks include such items as clearing an area within 4 feet of the work site and cleaning surfaces.  Sign the form and fax it to 6187.  The FM employee completing the work will also sign off on this form to acknowledge acceptance.

Please do not let this form hinder your inclination to report leaky pipes, etc.  The long-term damage from neglecting repairs can be expensive to fix and may generate safety hazards.

VI        REDUCING EXPOSURE TO CHEMICALS

Chemical safety is achieved through continual awareness of chemical hazards and by minimizing chemical exposures through the use of engineering controls (i.e. ventilation), personal protective equipment, and good lab practices.

A.  Ventilation

General room ventilation is not usually sufficient to prevent the accumulation of chemical vapors; therefore, when working with toxic chemicals, use a chemical fume hood.  There are many different types and sizes of hoods as well as other forms of local exhaust ventilation such as snorkels and vented chemical storage cabinets on campus.  Become familiar with the local exhaust ventilation units in your work area.  NOTE:  Biological Safety Cabinets are not designed for chemical ventilation!

1.  Ventilation failure

Fume hoods and other ventilation controls should provide enough ventilation to adequately remove the chemical hazard from the work area.  Be alert to detect any malfunction in the ventilation equipment.  In the event that a ventilation system fails, shut down all operations within that system promptly and safely.  Close or seal any open containers or equipment containing hazardous materials to prevent a release of vapors into the room.  If the ventilation equipment is a hood or a snorkel, post a sign on the item stating the hood or snorkel is not working properly.  Phone the FM Service Center (774-6547) and follow the procedures listed in section V part H.  Do not use chemicals in the hood or beneath the snorkel until further notice is given that the system has been repaired.  If the ventilation shut down creates an emergency situation (i.e. hazardous chemical vapors are not controlled), then evacuate personnel from the area, dial 911, and give as much detail as possible to the CMU Police Dispatcher (i.e. location, name of chemical, etc.). 

2.  Ventilation testing

The chemical fume hoods will be tested biannually by Facilities Management.  If any hood is not working properly, then it will be tagged out of service until the repairs are made.  While the hood is out of service, it cannot be used for chemical applications.

3.  Use of a chemical fume hood

Chemical fume hoods are protective equipment and must be used correctly to offer protection from chemical exposure.  The following is a list of procedures that must be followed to ensure that the ventilation is properly working at all times.

1.      Keep all laboratory doors to the hallway closed.  This will aid in keeping the hallways at a positive pressure and the laboratories at a negative pressure so chemical odors will not migrate out of the lab.  This is most pertinent to the occupants of the Dow Building, where the building is designed for the hallways to be positive to the labs. 

2.      Keep windows closed in the laboratory.  Drafts and eddy currents can cause turbulence at the face of the hood that may allow chemical vapors to escape from the hood.  Keeping the windows closed in the Dow Building will also aid in maintaining the proper air pressure gradient.

3.      Keep hood sashes in a lowered position with a maximum opening of 18 inches at all times except when actively positioning equipment.  The primary reason for this is safety.  The hoods are designed to eliminate chemical inhalation exposure.  When the sashes are wide open, the hood does not trap as much of the chemical vapor.  In addition, the total air balance of the building ventilation system is compromised when the sashes are left wide open in the Dow Building.  For your reference, the hoods have been marked with red tape at 18 inches.  When the hood is not in use, close the sash completely.  In this context, “not in use” means not being used to vent chemical vapors. 

4.      For hoods that contain manual flow controls, place the face velocity setting at 100 ft/min before using the hood.  Allow 3-5 minutes for the hood to stabilize and reach the new face velocity setting prior to beginning work.  A safe working range for a hood is 80-120 ft/min.  When the hood is not being used, the setting should be turned to minimum for standby mode.  To obtain a quick flush of the hood following a chemical spill in the hood, lower the sash to about an 8 inch open height, set the controller to 200 ft/min for a couple minutes, then return the controller to 100 ft/min for regular use.  Hoods that do not contain manual flow controls will be adjusted to maintain a face velocity of around 100 ft/min when turned on with the sash raised to 18 inches.

5.      Keep storage of chemicals and equipment in the hood to a minimum (i.e. only those materials in use).  If the hoods become cluttered, then airflow is blocked.  A spacious work area inside the hood will also allow the researcher more elbow room to work more efficiently.

6.  Place items at least six inches away from the front edge for better capture of vapors.

B.  Personal Protective Equipment (PPE)

1.  Responsible Parties

Supervisors and Principal Investigators are responsible for the Personal Protective Equipment (PPE) program in their laboratories.  This includes enforcement of the program and maintenance of the equipment.  Appropriate disciplinary action must be taken for repeated violation of this program.  Each Department must provide the necessary PPE for their employees.  To assist with PPE determinations, a PPE guide to hazard sources can be found in Appendix D.  NOTE:  If there are any questions on how to select PPE, contact the Safety Coordinator.

2.  Workplace Assessments

Perform a workplace assessment in each laboratory to determine if hazards requiring the use of PPE are present.  This is often a complex task; therefore sample copies of the workplace assessment forms can be found in Appendix D.  If potential hazards are present in the laboratory, do the following:

·        Identify each hazard and the source

·        Determine which body parts are affected

·        Select appropriate PPE against the hazard

·        Train each employee on the hazards present and when PPE should be worn

·        Train employees on the proper use, maintenance and limitations of each PPE device used

·        Maintain training records within the department 

·        Complete and maintain a workplace assessment form for each task or process performed in the laboratory that requires PPE

Do not rely upon PPE alone to completely protect against hazards.  Rather, use it in conjunction with effective engineering controls and workplace practices to minimize hazards in the workplace. 

Note:  The Michigan Safety Education and Training Division of Consumer and Industry Services provided the PPE guide to hazard sources, workplace assessments, and training documentation forms.

3.  Eye Protection

All safety eyewear must meet the ANSI Z87.1 standard for minimum allowable eye protection.  All eye protection supplied by Central Michigan University Departments must meet this standard.  Side shields are required, under Michigan law, on all safety glasses. 

Safety glasses do not give adequate protection from chemical splashes.  Note:  Some chemical eye and face protection does not afford impact protection.  If the potential for liquids to be splashed or sprayed is present, wear safety goggles.  When liquids are under extreme, high pressure, wear a face shield.  Never wear a face shield without wearing safety goggles underneath.

Contact lenses do not provide eye protection!  Wearing contact lenses is discouraged when working with materials or procedures that give off gases, vapors, welding fumes, smoke or dust.  If you choose to wear contacts, be aware of the hazards of wearing contacts in a lab.

Eye Protection is Required:

·        When working with or in the vicinity of solvents or corrosive chemicals, or with any chemical that could produce an eye injury

·        When working near equipment or apparatus under high pressure or vacuum, or when around equipment that could produce projectiles

·        When near laboratory benches where chemical reactions are being run or when around a radiation hazard

·        When transporting flammable, corrosive or toxic chemicals

·        During maintenance activities involving chemicals, hand/power or machine tools, welding, cutting, grinding, or abrasive blasting

·        When working behind hood doors or blast shields

4.  Gloves

Gloves provide protection against chemical, radiological and biological agents.  Selection of proper gloves for the work task is critical in maintaining protection against hazardous agents.  The Safety Coordinator can assist employees in the selection of proper gloves.  A glove selection table can be found in Appendix E.

Note the Following for Safe Glove Usage:

·        When working with corrosive liquids, solvents, or other potentially hazardous materials, wear proper gloves.  One type of glove will not protect against all chemicals; therefore proper glove selection is critical.

·        Remove gloves prior to answering phones, using computers, opening doors, or any other situation that might cause the spread of hazardous materials.

·        Remove gloves prior to leaving the laboratory area.

·        Wash hands anytime gloves are removed.

·        Be careful not to touch other parts of your body or apparel while wearing gloves (i.e. pushing up your glasses, etc.).

·        Dispose gloves as hazardous waste if they meet the characteristics of a hazardous waste (see section VIII part H).

5.  Respiratory Protection

Respirators are designed to keep the wearer from inhaling toxic chemicals or other contaminants in the air during accidents, emergencies or when engineering controls are not sufficient to maintain exposures below the Permissible Exposure Limit (PEL).  If you plan to use a respirator, see the Safety Coordinator prior to use.  Respirators have inherent hazards, should be considered the last line of defense, and should not be used during routine laboratory operation.  When required, respirators are available to employees at no cost.

Departments shall make every effort to use engineering and workplace controls to minimize exposures.  Respirators shall only be used when engineering controls and workplace practices fail to reduce the exposures below the PEL.  Departments are responsible for ensuring compliance with the Respiratory Protection Program.  Responsibilities include:

·        Inform the Safety Coordinator of potential health hazards that may require the use of respirators.

·        Ensure employees receive a respirator fit test prior to respirator usage.

·        Ensure employees have received proper medical and training clearance before they start using respirators.

·        Ensure employees use and store the respirator in compliance with the Respiratory Protection Program.

·        Ensure respirators are stored in a closed container, shelf, or cabinet.

·        Ensure respirators are kept clean and dust-free, and washed when necessary.

·        Ensure respirator cartridges are changed on a regular basis according to specifications or use limitations.  NOTE:  Cartridges may be a hazardous waste (see section VIII part H).

·        Require training for all employees using respirators.  Make sure training is recorded and on file with the Safety Coordinator.

·        Monitor the respirator program for compliance and report deficiencies to the Safety Coordinator.

6.  Laboratory Coats

Laboratory coats are issued to prevent the spread of hazardous materials outside the laboratory.  Protective clothing is also provided to prevent damage to employees’ personal clothing.  Protective clothing is only to be worn on site or for external activities relating to laboratory requirements where protective clothing is needed.  Remove contaminated clothing before leaving the laboratory area.

7.  Laboratory Attire

Wear appropriate clothing in the laboratory and animal rooms.  Shorts, short skirts, halter tops, high heels, sandals, open-toed shoes, and shoes with uppers constructed of woven material are not allowed.  Tie back long hair and loose clothing and remove dangling jewelry prior to working in the laboratory.

8.  Hearing Protection

If in the laboratory setting, a process is conducted with a high noise output, contact the Safety Coordinator to conduct a noise survey.  From this survey, the following items can be addressed:
