A job hazard analysis identifies hazards for a specific job through a systematic review of the tasks involved. It considers the relationship between the worker, tasks, tools, and environment. Potential hazards are identified and then controls are recommended, prioritizing engineering controls, then administrative controls, and finally personal protective equipment. The analysis should involve workers and focus on jobs with the highest injury rates or potential for serious harm.

Job Hazard Analysis A job hazard analysis is a technique that focuses on 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 uncontrolled hazards are identified, take action to eliminate them or reduce risk.
Performing a job hazard analysis is one of the best methods to develop safe work procedures for the equipment that is operated. The JHA can also be used to train employees in the hazards associated with task and what control measures should be practiced. Job Hazard Analysis
A Job Hazard Analysis requires the cooperation of all parties involved that includes: Safety Professional Engineers-Technical Advisor Supervisors-Frontline Personnel responsible for making change Employee-Person most familiar with job The JHA Team
Prioritization of JHA Jobs with the highest injury and illness rates Jobs that have the potential to cause serious injury Jobs in which one simple human error could cause injury Jobs complex enough to have written instructions Jobs that are new to you facility Jobs that significantly had changes in process technology or procedures
Steps for JHA Involve Employees Review accident history Conduct preliminary job review List, rank, and set priorities for hazardous jobs Outline the steps or tasks
Involvement of Employees They have a unique understanding of the job, and this knowledge is invaluable for finding hazards. Involving employees will help minimize oversights, ensure a quality analysis. Get workers to buy in to the solutions because they will share ownership
Outline the Steps Watch the employee perform the job and list each step as the worker takes it. Be sure to record enough information to describe each job action without getting overly detailed. Avoid making the breakdown of steps so detailed that it becomes unnecessarily long or so broad that it does not include basic steps.
Review the job steps with the employee to make sure you have not omitted something. Include the employee in all phases of the analysisfrom reviewing the job steps and procedures to discussing uncontrolled hazards and recommended solutions. Outline the Steps

Identifying the Hazards A job hazard analysis is an exercise in detective work. Your goal is to discover the following: What can go wrong? What are the consequences? How could it arise? What are other contributing factors? How likely is it that the hazard will occur?

Common Workplace Hazards Stressor Hazard Type Hazard Type Hazard Type Chemical Corrosive Fire Explosion Toxic Electrical Shock Short Circuit Fire-Static Mechanical Moving Parts Failure Noise Pressure Ergonomic Strain Human Error Fatigue
Stressor Hazard Type Hazard Type Hazard Type Radiation Ionizing Non Ionizing Contact Struck By Struck Against Caught In Environment Temp. Visibility Weather Misc. Slips Trips Falls Common Workplace Hazards
Controlling the Hazards The order of precedence and effectiveness of hazard control is the following: 1. Engineering controls 2. Administrative controls 3. Personal protective equipment
The most effective controls are engineering controls that physically change a machine or work environment to prevent employee exposure to the hazard. The more reliable or less likely a hazard control can be circumvented, the better. If this is not feasible, administrative controls may be appropriate. This may involve changing how employees do their jobs. Controlling the Hazards
Engineering Controls Engineering controls include the following: Elimination/minimization of the hazard Substitution of equipment or process to decrease hazard Isolation of the hazard with interlocks, machine guards, blast shields, or other means; and Removal or redirection of the hazard such as with local and exhaust ventilation.
Administrative Controls Administrative controls include the following: Written operating procedures, work permits, and safe work practices; Exposure time limitations (used most commonly to control heat stress and ergonomic hazards); Monitoring the use of highly hazardous materials; Alarms, signs, and warnings; Buddy system; and training
Personal Protective Equipment Personal Protective Equipment is acceptable as a control method in the following circumstances: When engineering controls are not feasible or do not totally eliminate the hazard; While engineering controls are being developed; When safe work practices do not provide sufficient additional protection; and During emergencies when engineering controls may not be feasible.
JHA Exercise #1 We are going to perform an exercise on grinding metal casting. Based on the steps, please identify the hazards and controls.
Exercise #2: Performing a Job Hazard Analysis
Summary Worksite hazard analysis consists of: oChange analysis oJHA oWorkplace inspections oHazard Reporting oTrend Analysis Effective programs will result in the identification of potential and existing hazards.
