15-hour Healthcare Laboratory Safety

The IOSHQ 15-Hour Healthcare Laboratory Safety program develops practical occupational safety and health knowledge for personnel working in clinical, medical, hospital and other healthcare laboratory environments.

Laboratories are controlled technical environments, but they are not hazard-free. Personnel may encounter biological materials, chemicals, sharps, glassware, electrical equipment, compressed gases, heat, moving equipment and other occupational hazards during routine laboratory activities.

Effective laboratory safety depends on recognizing these hazards before exposure occurs and applying controls appropriate to the material, equipment, procedure and potential consequences.

The program connects foundational occupational safety principles with practical hazard-control concepts relevant to healthcare laboratory work.

After successfully completing the assigned requirements of the program, participants should be able to:

1. Recognize Laboratory Hazards

   Identify common biological, chemical, physical, equipment and ergonomic hazards encountered in healthcare laboratory environments.

2. Understand Laboratory Risk

   Explain how exposure, potential consequences and existing controls influence occupational risk during laboratory activities.

3. Apply Risk-Control Principles

   Describe how elimination, substitution, engineering controls, administrative measures and PPE contribute to laboratory risk reduction.

4. Support Biological Exposure Prevention

   Recognize common routes of occupational exposure and precautions used to reduce contact with potentially hazardous biological materials.

5. Recognize Chemical Safety Requirements

   Use basic hazard-communication information to support safer handling, storage and response to laboratory chemicals.

6. Support Safe Laboratory Practices

   Recognize appropriate practices related to sharps, specimens, equipment, housekeeping and laboratory waste.

7. Respond Appropriately to Incidents

   Understand the importance of immediate response, reporting and referral following spills, exposures, injuries and other laboratory incidents.

8. Recognize the Limits of General Safety Training

   Identify situations requiring procedure-specific competency, technical expertise or additional authorization.

Healthcare laboratories support diagnosis, treatment and patient care through the collection, preparation, examination and management of specimens and related information.

These activities can expose personnel to hazards that may not always be visible. A specimen can contain potentially hazardous biological material, a chemical can present health or physical hazards and routine equipment can create mechanical, electrical or aerosol risks when used incorrectly.

Laboratory safety therefore depends on understanding both the immediate task and the hazards associated with the materials, equipment and procedures involved.

Hazard identification is the starting point for effective laboratory risk control.

Personnel should consider the biological or chemical properties of materials, routes of exposure, equipment being used, potential for aerosols or splashes, sharps, electrical sources, physical conditions and the consequences of equipment or procedural failure.

Hazards should be considered before work begins and reassessed when the procedure, material, equipment or working conditions change.

Risk assessment considers how exposure or injury could occur, who may be affected, the potential consequences and whether existing controls are adequate.

The same material can present different levels of risk depending on quantity, concentration, procedure, equipment, route of exposure and other working conditions.

Personnel should follow established laboratory risk assessments and procedures and seek appropriate technical guidance when work falls outside established conditions.

A systematic process helps connect laboratory hazard recognition with preventive action.

1. Identify

   Recognize the material, equipment, procedure or condition capable of causing harm.

2. Evaluate

   Consider potential exposure, routes of entry, consequences and existing safeguards.

3. Control

   Apply appropriate engineering, procedural and personal protective measures.

4. Perform

   Conduct the activity according to established laboratory procedures and precautions.

5. Respond

   Take appropriate action when a spill, exposure, equipment problem or other abnormal condition occurs.

6. Report

   Communicate incidents, near misses and significant deficiencies through applicable organizational channels.

7. Review

   Reassess controls when materials, equipment, procedures or working conditions change.

The hierarchy of controls provides a structured approach to reducing laboratory exposure.

Where feasible, hazards can be eliminated or replaced with less hazardous materials or methods. Engineering controls can contain or isolate hazards, while administrative measures establish procedures, access restrictions and work practices.

PPE provides an additional protective layer but should not automatically be treated as the only control when more effective measures are reasonably available.

Healthcare laboratories may receive specimens containing blood, body fluids, tissues or other biological materials that can present occupational exposure hazards.

The presence or absence of a hazard cannot always be determined by appearance. Appropriate precautions should therefore be applied according to established laboratory procedures and the nature of the material and activity.

Personnel should understand the exposure routes relevant to their work and the controls intended to interrupt those routes.

Occupational exposure can occur through needlesticks or other sharps injuries, contact with mucous membranes, contact with compromised skin, splashes or aerosols generated during certain laboratory procedures.

Understanding the potential route of exposure helps determine appropriate engineering controls, work practices and PPE.

Exposure prevention should focus on interrupting the pathway between the hazard and the worker rather than relying only on individual caution.

Specimens should be received, transported, opened, processed, stored and disposed of according to applicable laboratory procedures.

Containers should be suitable for their intended purpose and handled in a way that reduces leakage, breakage, splashing and contamination.

Damaged, leaking or otherwise abnormal specimen containers should be managed according to established laboratory procedures rather than handled as routine material.

Needles, lancets, broken glass and other sharp objects can create puncture or laceration hazards and may also provide a route for biological exposure.

Sharps should be handled only as necessary for the assigned task and disposed of promptly in the designated container according to workplace procedures.

Improvised handling, inappropriate disposal and unnecessary manipulation can increase the potential for injury.

Some laboratory activities can generate droplets, splashes or aerosols capable of spreading hazardous biological or chemical material.

Risk depends on the procedure, material, equipment and potential route of exposure.

Appropriate containment, equipment, work practices and PPE should be selected according to the applicable laboratory risk assessment and procedure.

Engineering controls reduce exposure by containing, isolating or otherwise controlling a hazard through the workplace or equipment design.

Depending on the activity, examples can include containment equipment, guards, ventilation systems, safety devices and appropriately designed sharps-disposal containers.

Engineering controls should be used correctly and maintained according to applicable requirements. A control that is damaged, bypassed or used incorrectly may not provide its intended protection.

Biological safety cabinets can provide important containment for designated laboratory activities when the correct equipment is selected, maintained and used appropriately.

Users should understand the operating practices applicable to the cabinet and avoid actions that unnecessarily interfere with its protective function.

General awareness does not replace the procedure-specific training required for personnel assigned to perform work requiring biological containment.

PPE selection should reflect the hazard, procedure and potential route of exposure.

Depending on the activity, laboratory PPE can include gloves, protective clothing and appropriate eye, face or other protection.

Personnel should understand how to use, remove and dispose of or maintain assigned PPE without creating unnecessary secondary exposure.

PPE should complement engineering and procedural controls rather than replace them without appropriate risk evaluation.

Hand hygiene is an important component of healthcare laboratory safety and infection prevention.

Personnel should follow the hand-hygiene requirements applicable to their work, including after relevant specimen or material handling and after removal of gloves where required by procedure.

Glove use does not automatically eliminate the need for appropriate hand hygiene.

Healthcare laboratories can use reagents, stains, disinfectants, solvents and other chemicals with health or physical hazards.

Chemical risk can involve inhalation, skin or eye contact, ingestion, fire, reactivity or other mechanisms depending on the substance.

Personnel should understand the hazards of chemicals used in their assigned work and follow applicable handling, storage and emergency procedures.

Labels and Safety Data Sheets provide important information about chemical hazards, precautions, storage and emergency measures.

Personnel should know how to locate and interpret the information relevant to chemicals used in their work.

Unlabeled or unidentified chemical containers should not be treated as safe merely because the material appears familiar.

Chemicals should be appropriately identified and stored according to their properties and applicable laboratory requirements.

Storage decisions should consider compatibility, container condition, environmental conditions and the consequences of leakage or breakage.

Chemicals should not be combined, transferred or stored based only on convenience when compatibility or other technical requirements need to be considered.

Laboratory equipment can create electrical, mechanical, thermal, pressure or other hazards depending on its design and use.

Personnel should operate equipment according to applicable instructions and laboratory procedures and should not bypass guards, interlocks or other protective features.

Equipment that is damaged, malfunctioning or behaving abnormally should be managed according to organizational procedures rather than continuing to be used without evaluation.

Centrifuges can create mechanical hazards and may contribute to specimen leakage or aerosol generation if equipment, containers or operating conditions are unsuitable.

Personnel should follow applicable procedures for loading, balancing, container selection, operation and response to abnormal conditions.

Maintenance or technical work beyond the user’s assigned responsibilities should be performed by appropriately qualified or authorized personnel.

Damaged glassware can cause cuts and can increase the potential for chemical or biological exposure when contaminated materials are involved.

Glassware should be inspected where appropriate and damaged items managed according to applicable procedures.

Broken contaminated glass should not be handled casually or placed into ordinary waste where specialized disposal arrangements apply.

Laboratory environments commonly use powered analytical instruments, refrigerators, computers and other electrical equipment.

Damaged cables, defective equipment, inappropriate connections and interaction between electricity and liquids can increase electrical risk.

Electrical faults should be reported and managed by personnel with the competency and authorization appropriate to the work.

Compressed-gas cylinders and related systems can present pressure, physical, chemical, fire or asphyxiation hazards depending on their contents and use.

Cylinders should be stored, secured, transported and used according to applicable organizational requirements.

Personnel should not modify regulators, connections or gas systems unless they are trained and authorized for the activity.

Laboratories can contain combustible materials, flammable substances, electrical equipment and other potential ignition or fuel sources.

Fire prevention includes appropriate chemical storage, control of ignition sources, electrical safety, housekeeping and maintaining clear emergency routes.

Personnel should understand applicable alarm and evacuation arrangements and the limits of their responsibilities during a fire emergency.

Good housekeeping supports contamination control, safe movement, equipment access and emergency response.

Work surfaces, floors, aisles and emergency equipment should not be unnecessarily obstructed by supplies, waste, packaging or unused equipment.

Housekeeping activities involving hazardous contamination should be performed according to the precautions and responsibilities established by the laboratory.

Laboratory personnel can perform repetitive pipetting, microscopy, computer work, prolonged standing and other activities capable of creating ergonomic stress.

Workstation arrangement, equipment placement, repetition, force, posture and work duration can influence musculoskeletal risk.

Where feasible, tasks and equipment should be arranged to reduce unnecessary reaching, sustained awkward posture and repetitive physical demand.

Laboratory waste can include biological, chemical, sharps and other materials requiring different handling and disposal arrangements.

Waste should be segregated and placed in the appropriate containers according to applicable organizational requirements.

Personnel should avoid mixing waste streams when doing so could create additional exposure, chemical reaction or disposal hazards.

Laboratory spills can involve biological materials, chemicals or other hazardous substances and may require different response methods.

Personnel should recognize when a spill can be managed within their assigned training and when the area should instead be isolated and additional assistance requested.

The correct response depends on the substance, quantity, location, exposure potential and applicable laboratory procedure.

Needlestick injuries, splashes, skin contact, inhalation events and other potential exposures should receive prompt attention according to organizational procedures.

Personnel should know how to access immediate first-response measures, report the exposure and obtain the appropriate medical or occupational health evaluation.

Potential exposures should not be ignored because the source appears low risk or because no immediate symptoms are present.

Healthcare laboratories should be prepared for emergencies relevant to their materials, equipment and facility.

Events can include spills, exposures, fire, equipment failure, power loss, medical emergencies and other abnormal conditions.

• Know applicable emergency contacts and reporting methods.
• Recognize relevant alarms and notifications.
• Understand evacuation arrangements.
• Know the location and purpose of applicable emergency equipment.
• Follow established spill and exposure procedures.
• Maintain access to emergency routes and equipment.
• Request specialized assistance when an event exceeds assigned capability.

Incidents and near misses can reveal weaknesses in laboratory procedures, equipment, training or controls.

Sharps injuries, spills, exposures, equipment failures and other relevant events should be reported according to applicable organizational requirements.

Near misses are valuable preventive information because they can identify risk before a similar event results in actual harm.

1. Respond

   Address immediate safety and exposure needs according to established procedures.

2. Report

   Notify the appropriate laboratory, supervisory, occupational health or safety personnel.

3. Record

   Provide accurate factual information about the event.

4. Evaluate

   Support review of relevant equipment, procedures and control conditions where assigned.

5. Correct

   Implement or support applicable corrective actions.

6. Learn

   Use relevant findings to reduce the likelihood of recurrence.

Laboratory safety depends on accurate communication of hazards, abnormal conditions and procedural requirements.

Personnel should report damaged equipment, spills, exposures, missing controls and other significant concerns through appropriate channels.

Technical uncertainty should be communicated rather than replaced with assumptions, particularly where biological, chemical or equipment hazards are involved.

Laboratory personnel should perform only those activities for which they possess the required training, competency and authorization.

When a condition falls outside an established procedure or an individual’s expertise, the matter should be referred to appropriate supervisory, laboratory safety, biosafety, chemical safety, occupational health or other technical personnel.

Recognizing when additional expertise is required is an important component of safe professional practice.
