A job hazard analysis is a technique that focuses on the job tasks as a way to identify hazards before they occur. It focuses on the relationship between the worker, the task, the tools, and the work environment. After identifying uncontrolled hazards, take steps to eliminate or reduce them to an acceptable risk level.

• 3-
• 1. Identify hazards associated with

each task (Job hazard analysis)

• 2. Assess hazard
• 3. Develop controls
• 4. Make risk based decisions
• 5. Implement controls
• 6. Supervise and evaluate

• 4-

 Identify the activity or tasks to be evaluated.  Break down the activity or task into distinct

• steps. Do not group too many steps into one.

 Identify the potential hazards for each of

those steps.

• 5-

 Indentify hazards associated with all job tasks and risk

levels

 Utilized a predetermined process for hazard evaluation  Summary table that can be easily understood.  Compatible with existing safety

protocols.

 Meets regulatory / accreditation

requirements

• 6-

 Assessment of hazards  Assignment of risk levels  Encompass work activities  Sign off by those performing

assessment

 Description of your assessment process

• 7-

 Employee job classifications covered  What activity / job are you covering  Provide some background information  Verbal summary of what found  Convey information to employees?

• 8-

 Summary table  Resources utilized  Management included and buy in  Outline what did, maybe what didn’t do?

• 9-

 Have “tools” available

Checklists, BioRisk, APHL, ACS, SA, WHO, etc. Helps to trigger questions in the assessment process.

 Not static, evolving!!!

Risk (assessment) is the probability of an adverse health effect as a result of exposure to hazards Communication is a fundamental part of risk assessment and training Effective risk management & safer workplaces

• 12-

 Risk Group organisms  Volume  Aerosol production  Clean up protocols  Sharps / safer medical devices  Training needs  Past accidents / incidents?  Emergency response adequate

• 13-

 Waste handling  Immunizations: Required / optional /

documentation

 Occupational heath program  Post exposure protocols  Disinfectant  Source of agent  Infectious dose / pathogenicity / virulence /

resistance / treatment / vaccines /

• 14-

 Biosafety Level 1 – 4

Most are at Biosafety level 2

 Biosafety Level 3

aerosol hazard but can treat

 Biosafety level 4

aerosol hazard and no treatment See BMBL, Biosafety in Microbiological and Biomedical Laboratories

• 15-

Risk Group Individual risk Community risk 1 no, low no, low 2 moderate low 3 high low 4 high high

• 16-

 Hazard chemicals, Global Harmonization

System, NFPA rating

 Carcinogens / teratogens / flammables

explosives / toxins

 Chemical inventory correct  Volume used / stored  First Aid and spill control adequate

• 17-

 Hazardous communication training

up to date

 Specific training needed  Storage and use appropriate  PEL, STEL’s, etc. air monitoring needed?  First aid materials / emergency response

• 18-

 Low vs high level radiation handling  Training adequate  Receipt material screened  Personnel exposure monitoring  Equipment properly maintained

and calibrated



User vs work in area

• 19-

 Slips, Trips & Falls  Flying objects  Electrical / Lock Out tag Out  Fall protection  Hearing, Hearing

Conservation Program

 Ergonomics

• 20-

 Biosafety cabinet  Chemical fume hood  Centrifuge bucket caps  Cap removal blood tubes  Building ventilation  Levels of containment, i.e. plastic bags  Specimens Category A packaging  Safer medical devices

• 21-

• 22-

 Training  Competency  # employees performing duties  How long perform duties / breaks  Do you do it in the first place!!??  Is there a better way to do it?!!  Spill clean up materials  Operator manuals available / knowledgeable  Hair tied back? Loose clothing  Accident history

• 23-

 After Administrative and Engineering

controls implemented

 Institution have a basic clothing policy  Lab coats  Gowns  Gloves  Respirator  Surgical mask respirator

• 24-

 Formaldehyde, for example

Passive monitor / send

• ut for testing

• 25-
• Data used in conducting risk assessments are based
• n incomplete knowledge
• Unlike chemicals, many biological agents can

replicate and the concentration of organisms is rarely precisely known.

• Risk groups are a starting point and do not

necessarily equate to biosafety levels
