Types of Work Place Hazards
Unsafe Act - Performance of a task or other activity that is
conducted in a manner that may threaten the health and/or safety
Examples are :
Operating without qualification or authorization.
Lack of or improper use of PPE.
Failure to tagout/lockout.
Operating equipment at unsafe speed.
Failure to warn.
Bypass or removal of safety devices.
Using defective equipment.
Use of tools for other than their intended purpose.
Working in hazardous locations without adequate
protection or warning.
Improper repair of equipment.
Wearing unsafe clothing.

Unsafe Condition - A condition in the work place
that is likely to cause property damage or injury.
Defective tools, equipment, or supplies.
Inadequate supports or guards.
Congestion in the workplace.
Inadequate warning systems.
Fire and explosion hazards.
Hazardous atmospheric condition.

Purpose of Job Hazard Analysis
• A hazard analysis is the evaluation of the hazards
associated with an employee’s work activity
• A hazard analysis focuses on “fixing” the system or
root causes that brought the hazardous condition or
unsafe practice into the workplace
– Provides organized approach for the evaluation of
– Identifies hazards, root causes and corrective
• A hazard analysis attempts to incorporate “Safe
Behavior” – Behaviour-based Safety (BBS) into the
normal operating procedures.
Hazard Analysis for OSH
• OSH Committee must:
– Identify hazards in the
workplace that could
result in injury or illness
– Evaluate the level of
risk to help determine
what controls to
– Select an appropriate
solution to control the
hazard and/or protect
• Potential root causes of injuries
– Lack of knowledge
– Lack of physical ability
– Prior training that included
– Previously unidentified
– Newly introduced hazard
resulting from process or
• Engineering controls eliminate
exposure to the hazard by:
- Isolating the employee from
- Improving (redesign) work
- Substituting less hazardous
- Modifying equipment
• Administrative controls
reduce employee exposure to
a hazard by:
– Reducing the frequency of
performing the hazardous
– Rotating employees to
reduce exposure time
– Training employees to
recognize hazards and
employ safety practices.
• Work practice controls include:
– Workplace rules
– Safe & healthful work practices
– Personal hygiene
– Housekeeping and maintenance
– Procedures for specific operations
• OSHA requires employers to
provide PPE to reduce employee
exposure to hazards when
engineering and administrative
controls are not feasible or
• PPE alone should not be relied on
to protect against hazards; other
uses include guards, engineering
controls, and sound manufacturing
• Assess how well the JHA process is “fixing” hazardous
– Updating JHAs for routine and non-routine task
– Ensuring JHAs were developed for all new processes
– Conducting routine self-inspections
– Examining Industrial Hygiene reports
– Reviewing investigation findings for injuries and near
– Following up on employee concerns.
