Lab Warning

Laboratory Health and Safety Manual

Section 1: Introduction and Objectives

This manual provides a set of minimum standards and practices for the safe and healthy operation of a laboratory. Following the requirements set out in the manual will help meet the requirements of the Occupational Health and Safety Act of Ontario (OHSA) for the purposes of the operation of a laboratory. It is required reading for all laboratory supervisors, researchers, staff, and students working in research and teaching laboratories at Carleton University.

The manual was developed by Environmental Health and Safety Services (EHSS) based on the Laboratory Health and Safety Manual from the University of Western Ontario, and in consultation with faculty and staff in the Faculties of Science and Engineering, the Department of Physical Plant, and the Joint Occupational Health and Safety Committee. Revisions and updates will continue to be made. Please contact EHSS with any comments or suggestions you have about the manual.

This manual is intended to:

• Define health and safety responsibilities within the University community;
• Outline specific policy application for laboratory operation;
• Explain basic emergency procedures; and
• Provide information and standards for the healthy and safe operation of a laboratory.

The manual is not all encompassing. There are many special procedures conducted within our laboratories, which require unique health and safety precautions.
Departments will have additional procedures that apply to their own situations and work. In all cases the laboratory supervisor is ultimately responsible for teaching safe work practices and must insist upon the use of proper procedures to eliminate unnecessary hazards.

If you have any questions about how to safely undertake a task or project, ask your supervisor before you begin.

The objectives of this manual are to:

• Define who is a supervisor and who is a laboratory worker;
• Define the responsibilities of the supervisor and the laboratory worker for the safe operation of a laboratory;
• Highlight sections of the OHSA which affect the operation of a laboratory;
• Provide a standard of good laboratory safety practices which also allows the University to meet the requirements of Section 25(2)h of the OHSA, An employer shall take every precaution reasonable in the circumstances for the protection of a worker.
• Provide the general guidelines and basic rules considered the minimum for the safe operation of a laboratory at Carleton University;
• Protect all laboratory users from health and safety hazards;

Implementation Safety System

Implementing the right safety system can increase productivity while helping to mitigate risk and minimize costs. Thanks to advances in automation technology increasingly cohesive global standards and a manufacturing culture keep on protecting people and optimizing machines, manufactures have the best opportunity ever to employ an integrated system that improves productivity without compromising safety.

Rockwell automation offers a large line of innovative safety automation products and services, providing customers with a single, trusted source for all their safety automation needs.

Conventional Safety System
Many legacy manufacturing applications were developed without an emphasis on safety, relying on the operator and maintenance technician to avoid hazards. Other was deployed as an after thought, in response to an accident or new industry standard. These safety ad-ons used a “black-box” approach where the safety solution were completely separate from the automation system, contributing to a reactive manufacturing environment.

Integrated Architecture Solution
The risk associated and conventional systems are no longer needed or acceptable, thanks to progressive global standard, major technological innovation and risk management services. When deployed properly using a holistic approach today’s safety automation system allows the best of both worlds, a safety environment for employees, reduced environmental impact better processes and optimized productivity.

Innovation Safety Technology Systems
The inherent properties of automation solutions make it easier for costumers to cost effectively integrate safety. The transition from electromechanical relays to solid state device brings a host of new benefits including improved diagnostic, improved reliability and better space efficiency. Likewise the integration of safety control into network based architectures provide valuable plant-floor information that can be used to optimize production and help reduce downtime.

The ability to implement safety control within a single network architecture offers many advantages over hardwiring, including reduced design, installation and maintenance cross as well as expanded diagnostic capabilities. New safety control technology also help streamline lock-out procedures, improving productivity while minimizing the desire for operators to bypass the safety system.

Additionally the practice of designing in safety up front helps machine builder evaluate and mitigate risks early in the process, saving critical time and helping you get machines to market faster. Innovative safety technologies make it possible to use zone control and safe speed for maintenance and repairs. This combine with the ability to streamline hardware helps machines use less energy, require less downtime and be more productive.

Frostbite

Frostbite is local issue damage as a consequence of impaired blood flow caused by exposure to cold, moisture, and wind.

 

Frostbite can occur already at temperature of +6^oC and below with high humidity, and/or frost. The cold brakes blood supply to the affected tissue. Highly at risk are those parts of the body with little protection by muscles and tissue (toes, fingers, cheeks, nose, and ears), and parts of the body is tight clothing (e.g. shoes, boots).

 

Symptom and signs

The assessment of the Frostbite is extremely difficult and only possible after several days. If in doubt always suspect frostbite.

 

Superficial frostbite (frost nip):

-          initially numbness and pallor

-          later prickling pain and blue red discoloration

 

Deep frostbite:

-          blister formation and white to grey-blue mottled discoloration of the skin

-          impaired motility of the affected part

-          lack of feeling (when touched)

-          intense pain

 

Danger!

Necroses of the tissue result in permanent damage of the affected parts.

 

First Aid

-          Loosen tight clothing

-          Place a sterile dressing over the affected part.

-          Give the casualty hot, sugared drinks, but no alcohol

-          Warm the casualty with additional clothing or blankets

-          Take the casualty to a doctor or hospital

 

Attempt to normalize blood flow through the frozen part by giving hot drinks and by warming up the rest of the body. The affected part must not be warmed up directly or rubbed with snow or massaged with a terry towel.

Ice accidents:
To help people that have an ice accident, do the following procedure:

• Ask the casualty to place both arms on the ice surface and to move as little as possible.
• Make an emergency call.
• Don’t attempt to rescue the casualty without being secured by a rope or safe-guarded by a second helper.
• Use devices, such as planks, boards, ladders, poles.
• Check the carrying capacity of the ice, and make sure that the ice will carry both the helper and the casualty!
• Use something wide as a support when you approach the casualty.

Bathing Accidents:
To help people on getting bathing accident, follow the procedure bellow:

• Make an emergency call.
• Rescue the casualty by means of a boat or toss him a life-belt or life-buoy on a lifeline.
• Don’t swim in unfamiliar waters because of e.g. depths, large distances, strong currents, waves, nature of the banks, weirs.
• Jump only in a squatting position.
• Swim to the casualty with a floating device that will help to support the casualty (e.g. air mattress, life belt).

If the casualty is about to grab you:

• Swiftly dive below the casualty.
• If the casualty is clutching you, free yourself at all costs (release grips).

More safety – attend a lifeguard swimming course
Training courses and exams are held by the Austrian Water Rescue System) comprising the organizations listed below: Junior Red Cross, Federal Army, Life saving Association, etc.

Moving the casualty to safety (rescue grips):

Dragging:
Cross the casualty’s arms below his head and drag him to safety. When doing so, lift the casualty’s body as little as possible.

• Rautek Grip:

Before moving the casualty from the car, make sure that:

• The engine of the accident vehicle is turned off (leave the ignition key in place).
• The casualty’s legs are not trapped.
• The safety belt has been opened by the helper, and
• The casualty is slightly bent forward.
• Now lift the casualty with the Rautek grip and pull him out of the car in such a way that the casualty leans against your thigh. In this way you move the casualty away from the danger zone. If the second helper is present, he lifts the casualty’s legs.

Personal Protective Equipment

Section 9: Personal Protective Equipment

Personal protective equipment (PPE) is designed to protect many parts of the body. It should act as a primary barrier between the hazard and the worker. It does not reduce the hazard. Personal protective equipment appropriate to the hazards must be worn. (Ontario Regulation 851 Sections 79-86)

All personnel in a laboratory should consult with their supervisor regarding protective equipment appropriate to the individual laboratory. (Ontario Regulation 851 Section 79) It is the responsibility of the supervisor to select the PPE appropriate to the work being done. The Canadian Standards Association publishes standards with information that may assist the supervisor with the selection. In some cases the department will pay for the PPE, in other cases PPE may be provided from research grant funds, or students may be required to purchase their own PPE.

It is the responsibility of anyone working in the lab to use the PPE that is required.
Personal protective equipment must not be considered the primary means of protecting the laboratory worker. Research procedures and engineering controls, such as fume hoods, must be considered first.

All the personnel in the lab should wear personal protective equipment, not just those actively working. Appropriate clothing should be worn at all times.

1. Gloves
   There are many different types of protective gloves available and they should be chosen to offer the best protection for specific procedures and chemicals. Glove materials have different chemical resistances and should be checked with the manufacturer prior to selecting a specific type of glove.
   Always check the integrity of the glove before starting work.
   Use the correct technique to remove gloves before leaving the laboratory. Consider gloves to be contaminated after use and dispose of appropriately.
2. Eye Protection
   An individual exposed to possible eye injury shall wear eye protection appropriate to the circumstances. Approved safety glasses with side shields are the minimum protection required in a laboratory. Goggles and face shields may also be required for certain procedures, as determined by the supervisor.
   In those cases where prescription safety glasses are required, the individual will provide them. Such glasses must meet all the requirements for safety glasses as specified by the CSA Standard for Eye and Face Protectors (CSA-Z94.3-99).
3. Skin Protection
   Clothing should provide maximum coverage of skin in accordance with the risk of exposure. The supervisor should determine the specific requirements in each lab.
   When lab coats are used they should be
   • removed and hung up prior to personnel leaving the lab,
   • laundered separately from other clothing,
   • buttoned closed when worn.
   Rubber aprons should be worn when handling highly corrosive or reactive materials.
4. Respiratory Protection
   Under normal circumstances respirators should not be required for laboratory situations. Use of fume hoods should generally eliminate respiratory hazards. If a respirator is required, the selection should be based on the CSA Standard, Selection, Use and Care of Respirators CSA – Z94.4-93. It is essential the wearer be properly instructed for fit and safe use of a respirator.
5. Hearing Protection
   Hearing protection is required for noise levels above 90 dBA. (Ontario Regulation 851 Section 139) The supervisor will determine the appropriate type of hearing protection to be worn. (Hearing Protectors CSA-Z94.2-M1984) Measuring can be done by EHSS.
6. Foot Protection
   Safety footwear is designed to protect feet against a variety of injuries. Impact, compression, chemical splashes and puncture are the most common types of injuries. Footwear should be chosen according to the hazard and should be properly rated. (Protective Footwear CSA-Z195-M92)
7. Head Protection
   Head protection is required when working where there is a risk of injury from moving, falling, or flying objects or when working near high-voltage equipment. Hard hats are designed to protect from the impact and penetration caused by objects hitting the head or from limited electrical shock or burns.

Basic Safety Procedures

Section 6: Basic Safety Procedures

6.1 Procedures for Unattended Work

1. Unattended procedures should be kept to a minimum.
2. An unattended procedure must be visited periodically and a sign posted on the door of the lab outlining the procedure with the name and phone number of a contact person. The sign will indicate the date and time the procedure was started, when it is expected to be completed, and when it was last checked. (See Appendix 13)
3. Unattended procedures using cooling water must have the hoses securely attached and the water adjusted to the minimum flow necessary. Ensure plumbing drains are clear before leaving the procedure.

6.2 Working Alone

1. For safety reasons working alone should be avoided. Someone should always be within call when a laboratory procedure is being performed.
2. For work with hazardous materials or procedures the supervisor has the right to require that at least one other person be present.

6.3 Housekeeping

1. Work areas must be kept clean and free of obstructions.
2. Stairways and halls must not be used for storage. This applies to both equipment and personal property. Bicycles are not allowed in buildings.
3. Walkways and aisles in laboratories must be kept clear.
4. Access to emergency equipment or exits must never be blocked. (Ontario Regulation 851 Section123 (2))
5. Equipment and chemicals must be stored properly.
6. Spilled chemicals must be dealt with immediately and if safe cleaned up by the chemical user. (See Section 11.4 of this manual) Spills must be reported to the supervisor.
7. Wastes must be placed in appropriate, labeled containers.
8. Materials no longer used must not be allowed to accumulate and must be disposed of following proper procedures. (See Appendix 4, Disposal of Hazardous Waste)

6.4 Laboratory Equipment Maintenance

Laboratory equipment must be inspected and maintained by a qualified person. The frequency of the inspection depends on the hazard posed by the equipment, the manufacturer's instructions, or as required by regulations. Records of the maintenance must be kept on file by the laboratory supervisor and be available at all times.

6.5 Guarding

1. All mechanical equipment must be adequately guarded to prevent access to electrical connections or moving parts. (Ontario Regulation 851 Section 25)
   b) All centrifuges must be fitted with an interlock so that they cannot be accessed while moving or started while open. (Ontario Regulation 851 Section 31)

6.6 Shielding

1. Appropriate shielding must be used whenever an operation involves chemicals with the potential for explosion or severe splashing. Examples include:
   • when a reaction is attempted for the first time;
   • when a familiar reaction is carried out on a larger scale than usual;
   • whenever operations are carried out under non-ambient conditions; or
   • Whenever a severe splashing potential exists for corrosive materials. (Ontario Regulation 851 Section 89)
2. Shielding or equivalent precautions are to be used when working with non-ionizing radiation sources, magnetic and other fields. Examples include:
   • Lasers
   • Infrared radiation
   • Ultraviolet radiation
   • Microwave radiation
   Refer to the Radiation Safety Manual (available from EHSS) for shielding of ionizing radiation sources.
3. Appropriate shielding is required when using equipment with thermal hazards.

6.7 Glassware

1. Repair or dispose of any damaged glassware. Follow proper disposal procedures for damaged glassware. (See Appendix 4)
2. Ensure adequate hand protection is used when working with glass tubing.
3. Tape permanent vacuum glassware which presents an implosion risk with either electrical or duct tape or use appropriate shielding. (Ontario Regulation 851 Section 84 (b & f))
4. Wear appropriate hand protection when picking up broken glass.
5. Ensure proper instruction is given for the use of specialized glassware.
6. Specific procedures may apply for contaminated glassware.

6.8 Flammable and Combustible Material Hazards

1. Use an open flame only as long as necessary and extinguish it when done.
2. Do not use an open flame to heat flammable or combustible materials. It is generally not recommended to perform a distillation at reduced pressure using an open flame due to the possibility of local superheating.
3. Remove all flammable and combustible materials from the work area before lighting a flame.
4. Notify all others in the lab and note any procedure using flammable and combustible gases and liquids before lighting a flame.
5. Store all flammable and combustible materials properly as required by the Ontario Fire Code. (See Appendix 5, Storage and Handling of Flammable and Combustible Liquids)
6. Avoid open flames, use non-sparking equipment and adequate ventilation if a flammable atmosphere may be generated, for example when dispensing flammable or combustible solvents. (Ontario Regulation 851 Section 63)

6.9 Cryogenic Materials and Cold Traps

1. Wear proper gloves and a face shield when preparing or using a cold trap below –70 degrees C or cryogenic liquids.
2. Never use liquid nitrogen or liquid air as a cold trap to collect a flammable or combustible material mixed with air. Oxygen may condense from the air and lead to an explosion hazard.
3. Always ensure the flammable or combustible material is collected under vacuum. Use a Dewar vessel designed for cryogenic liquids not a regular domestic vacuum flask.
4. When returning the cooled material back to atmospheric pressure, ensure the cryogenic coolant has been removed to prevent liquid air condensation.
5. Use appropriate gloves when handling cryogenic materials, e.g. dry ice, etc.
6. Dry ice/solvent cooling baths should be prepared carefully by the slow addition of small amounts of the solid dry ice to the solvent to avoid excessive frothing and overflow of the solvent.
7. Never lower your head into a dry ice chest since a high level of CO2 may accumulate there posing an asphyxiation hazard.

6.10 Systems under Pressure

1. Never heat or carry out a reaction in a closed vessel unless it is designed or tested to withstand the expected pressure of the reaction.
2. Pressurized equipment must have an appropriate pressure release valve.
3. Pressurized equipment must be shielded, guarded, or designed to protect the operator against potential explosions.

6.11 Back Flow Preventers

1. All water faucets to which a hose is attached in a laboratory must be equipped with an appropriate backflow preventer. (Ontario Building Code) This prevents the contamination of the drinking water system. Contact the Manager, Maintenance Services at extension
2. 8821 for an evaluation.

6.12 Electrical Equipment and Apparatus

1. All electrical installations must conform to the provisions of the Power Commission Act of Ontario.
2. All electrical equipment must be CSA approved or inspected by Ontario Hydro.
3. Extension cords must not be used for permanent installations. Contact Physical Plant at 3668 to install or relocate outlets in close proximity to the equipment.
4. Use ground fault circuit interrupters where there is a risk of an operator coming in contact with water and electrical equipment simultaneously.
5. Only trained, qualified personnel may repair or modify electrical or electronic equipment.
6. Power bars should not be located beneath work benches where chemicals are handled.

6.13 Compressed Gas Cylinders

All compressed gases have potential health and safety hazards related to the chemical properties of the gas, as well as pressure hazards. Take precautions to protect personnel from these potential hazards

1. All gas cylinders, empty or full, must be properly secured so they cannot be knocked over. Cylinders with safety caps in place may be secured together. All others must be secured separately. (Ontario Regulation 851 Section 49)
2. Compressed gas cylinders should be transported capped and chained on appropriate carts.
3. Always wear eye protection when working with compressed gases.
4. Always use the appropriate regulator for the gas being used. The regulator should be inspected each time before use, as recommended by the manufacturer.
   Note: Failure of either the diaphragm or the regulator can occur unexpectedly. Be prepared. When opening the main valve of a compressed gas cylinder do not stand over the main valve or behind or in front of the pressure gauge(s). These are the most probable locations for failure.
5. Ensure the tubing and the apparatus downstream from the regulator are designed to withstand the pressures intended to be delivered. The tubing and other components should also be chemically resistant to the gas being used.
6. Never use PTFE (Teflon) tape, other lubricants or sealant when installing a regulator. The recommendation of commercial gas suppliers is that regulator fittings in good condition do not require additional sealants.
7. Ensure all installations are designed to prevent the hazardous combination of gases except as required by the use.
8. Take appropriate precautions to prevent exposure of yourself or others to the other hazardous properties of the gas used. Consult the safety data sheet.
9. Compressed gas cylinders have a finite shelf life. Ensure cylinders are regularly inspected. Any cylinder that is corroded or has damaged valve components should be returned to the supplier. All cylinders older than ten years should be returned to the manufacturer. Manufacturers of corrosive gases recommend that cylinders of corrosives be replaced every six months to guard against valve failure.
