JHA Purpose

Taking a job or task and breaking it downinto steps to identify hazards and correctthat may cause injury to employees.

Effective JHAs help the employerrecognize and control hazards andexposures in the workplace.

Why do new workers have a higher rate ofdisabling claims.

How might the employees perception of ahazard differ from that of the employer or

supervisor (or safety person)?

Why is it important to involve the employee?

Why is a JHA more effective than walk-aroundinspections in reducing accidents in theworkplace?

Determine Probability and Severity

How hazardous is the job?


8/12/2019 4-jha

12/44

Probability

The chance that a given event will occur.


8/12/2019 4-jha

13/44

Probability

Can be determine based on the following: The number of employees exposed; The frequency and duration of exposure; The proximity of employees to the danger zone; Factors which require work under stress;


8/12/2019 4-jha

14/44


Probability

Can be determine based on the following: Lack of proper training and supervision or

improper workplace design; or Other factors which may significantly influence

the degree of probability of an accidentoccurring.

8/12/2019 4-jha

15/44

The probability rating is:o Low- If the factors considered indicate it

would be unlikely that an accident could occuro

Medium- If the factors considered indicate itwould be likely that an accident could occuro High - If the factors considered indicate it

would be very likely that an accident could

occur

16/44

Severity

The degree of injury orillness which isreasonably predictable.

17/44

SERIOUS HAZARDS:Could cause an accidentor health hazard exposure resulting in serious

physical harm.OTHER THAN SERIOUS HAZARDS:Lack thepotential for causing serious physical harm, but

could have a direct impact on employee safetyand health.

The Hierarchy of Controls

8/12/2019 4-jha

34/44

Engineering Controls

Consist of substitution, isolation, ventilation, andequipment modification.

These controls focus on the source of thehazard, unlike other types of controls that

generally focus on the employee exposed to thehazard.

The basic concept behind engineering controls isthat, to the extent feasible, the work environmentand the job itself should be designed to eliminatehazards or reduce exposure to hazards


8/12/2019 4-jha

35/44

Safe Work Practices

General workplace rules and other operation-specific rules

Respiratory Protection Lockout/Tagout

Confined Space Entry Hazard Communication Blood borne Pathogens Hearing Conservation


Administrative Controls

8/12/2019 4-jha

36/44

Administrative Controls

Measures aimed at reducing employee exposureto hazards

Providing variety in jobs Adjusting work schedules and work pace Providing recovery time Modifying work practices Ensuring regular housekeeping and maintenance

of work spaces, tools, and equipment Encouraging exercise

Used in conjunction with other controls5. Develop Control Measures

8/12/2019 4-jha

37/44

Personal Protective Equipment

When exposure to hazards cannot beengineered completely out of normal operations

or maintenance work, and when safe workpractices and administrative controls cannotprovide sufficient additional protection fromexposure, personal protective clothing and/or

equipment may be required.
