Assessment Date: [DATE]

Assessor: [ASSESSOR NAME]

Department/Area: [DEPARTMENT/AREA]

Review Date: [REVIEW DATE]

1. Assessment Scope

This Job Hazard Analysis (JHA) covers the assembly of a 1000-component product, from initial component staging to final product inspection and packaging. It includes all tasks performed by assembly personnel, material handlers, and quality control staff within the designated assembly area. Excluded are tasks related to component manufacturing, machine maintenance performed by specialized technicians, and activities outside the defined assembly area.

2. Risk Assessment Methodology

This risk assessment employs a 5x5 risk matrix to determine risk ratings based on likelihood and severity. The hierarchy of controls is applied to identify and implement control measures, prioritizing elimination and substitution, followed by engineering controls, administrative controls, and finally, personal protective equipment (PPE). The JHA team includes assembly workers, supervisors, and a safety representative to ensure comprehensive hazard identification and effective control implementation.

3. Risk Matrix Reference

The following matrix is used to evaluate risk levels based on likelihood and severity:

		Likelihood
Rare	Unlikely	Possible	Likely	Almost Certain
Severity	Catastrophic	Low	Low	Medium	Medium	High
Major	Low	Medium	Medium	High	Extreme
Moderate	Medium	Medium	High	Extreme	Extreme
Minor	Medium	High	Extreme	Extreme	Extreme
Negligible	High	Extreme	Extreme	Extreme	Extreme

• Maintain a clean and organized work environment.

Regularly clean work areas, remove clutter, and properly store materials to prevent trips, falls, and other hazards.

• Provide adequate lighting in all work areas.

Ensure sufficient lighting levels to allow workers to see clearly and avoid eye strain. Supplement natural light with artificial lighting as needed.

• Implement a comprehensive hazard communication program.

Provide workers with information and training on the hazards of chemicals and other materials used in the assembly process. Ensure that Safety Data Sheets (SDS) are readily available.

• Ensure all equipment is properly guarded.

Install and maintain machine guards to protect workers from moving parts and other hazards.

• Provide and enforce the use of appropriate personal protective equipment (PPE).

Conduct a PPE assessment to determine the appropriate PPE for each task. Provide workers with the necessary PPE and ensure that they are properly trained on its use and maintenance.

6. Emergency Preparedness

• In case of a fire, activate the nearest fire alarm, evacuate the area, and proceed to the designated assembly point. Do not re-enter the building until authorized by emergency personnel.

• In the event of an injury, provide first aid, and seek medical attention if necessary. Report all injuries to the supervisor and complete an incident report.
• If there is an electrical incident, immediately shut off the power source if safe to do so, and call for qualified assistance. Keep people away from the area until it is declared safe.

7. Training Requirements

• Hazard Communication Training: Workers must be trained on the hazards of chemicals and other materials used in the assembly process, including how to read and interpret Safety Data Sheets (SDS).
