Job Hazard Analysis for Stacked Work Procedures in the Elevator Industry

Assessment Date: [DATE]

Assessor: [ASSESSOR NAME]

Department/Area: [DEPARTMENT/AREA]

Review Date: [REVIEW DATE]

1. Assessment Scope

This Job Hazard Analysis (JHA) covers all tasks associated with stacked work procedures in the elevator industry. This includes, but is not limited to, the assembly of elevator components in a stacked configuration, the installation of stacked elevator systems, and the maintenance and repair of existing stacked elevators. The scope encompasses all personnel involved in these activities, including elevator mechanics, technicians, and supervisors. Excluded from this JHA are tasks not directly related to stacked work, such as the installation of single elevators or general facility maintenance.

2. Risk Assessment Methodology

This risk assessment employs a 5x5 risk matrix to evaluate the likelihood and severity of potential hazards. The methodology follows a systematic approach: 1) Identify hazards associated with each step of the stacked work procedure. 2) Assess the initial risk level based on the likelihood and severity of potential consequences. 3) Implement control measures based on the hierarchy of controls (Elimination, Substitution, Engineering Controls, Administrative Controls, and PPE). 4) Evaluate the residual risk level after implementing control measures. 5) Continuously monitor and review the effectiveness of control measures, updating the JHA as needed.

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	Low	Medium	Medium	High
Moderate	Low	Medium	Medium	High	Extreme
Minor	Medium	Medium	High	Extreme	Extreme
Negligible	Medium	High	High	Extreme	Extreme

4. Hazard Identification and Risk Evaluation

1. Falls from height during the assembly or installation of stacked elevator components.

Potential Consequences: Serious injury or death.

Affected Persons: Workers, public

Initial Risk Assessment

Likelihood	Severity	Risk Rating
Possible	Major	High

Control Measures

• Use fall arrest systems (harnesses, lanyards, lifelines).
• Install guardrails and safety nets.
• Implement a fall protection plan.

Residual Risk Assessment

Likelihood	Severity	Risk Rating
Unlikely	Major	Medium

2. Electrical shock or electrocution while working on elevator wiring or control systems.

Potential Consequences: Burns, cardiac arrest, or death.

Affected Persons: Workers

Initial Risk Assessment

Likelihood	Severity	Risk Rating
Possible	Major	High

Control Measures

• De-energize and lockout electrical circuits before working on electrical components.
• Use insulated tools and equipment.
• Ensure proper grounding of equipment.

Residual Risk Assessment

Likelihood	Severity	Risk Rating
Unlikely	Moderate	Medium

3. Dropped objects striking workers or members of the public below.

Potential Consequences: Head injuries, lacerations, or fractures.

Affected Persons: Workers, public

Initial Risk Assessment

Likelihood	Severity	Risk Rating
Possible	Moderate	Medium

Control Measures

• Use tool tethers and safety nets to prevent dropped objects.
• Establish exclusion zones below work areas.
• Regularly inspect tools and equipment for defects.

Residual Risk Assessment

Likelihood	Severity	Risk Rating
Unlikely	Minor	Low

4. Musculoskeletal injuries (MSIs) from lifting, pushing, or pulling heavy elevator components.

Potential Consequences: Strains, sprains, or back injuries.

Affected Persons: Workers

Initial Risk Assessment

Likelihood	Severity	Risk Rating
Likely	Moderate	Medium

Control Measures

• Provide ergonomic training on proper lifting techniques.
• Use mechanical aids (hoists, cranes) to lift heavy components.
• Implement a buddy system for lifting and moving heavy objects.

Residual Risk Assessment

Likelihood	Severity	Risk Rating
Possible	Minor	Low

5. Exposure to dust, fumes, or chemicals during elevator installation or maintenance.

Potential Consequences: Respiratory irritation, allergic reactions, or long-term health effects.

Affected Persons: Workers

Initial Risk Assessment

Likelihood	Severity	Risk Rating
Possible	Moderate	Medium

Control Measures

• Ensure adequate ventilation in the work area.
• Use respiratory protection (e.g., respirators) when working with dust or fumes.
• Implement a hazard communication program for chemicals used in elevator work.

Residual Risk Assessment

Likelihood	Severity	Risk Rating
Unlikely	Minor	Low

5. General Control Measures

• Conduct regular workplace inspections to identify and correct hazards.

Implement a system for reporting and tracking hazards identified during inspections. [1]

• Ensure all workers receive comprehensive training on safe work procedures, hazard identification, and control measures.

Maintain records of all training activities.

• Enforce strict adherence to lockout/tagout procedures during maintenance and repair activities.

Regularly audit lockout/tagout procedures to ensure compliance.

6. Emergency Preparedness

• In the event of a fall from height, immediately activate the emergency response system and provide first aid.
• For electrical hazards, ensure the power is shut off and lockout/tagout procedures are followed before providing assistance.
• In case of a dropped object, clear the area and inspect for any damage to equipment or structures.

7. Training Requirements

• Fall Protection Training: Workers must be trained on the proper use of fall protection equipment, including harnesses, lanyards, and lifelines.
• Lockout/Tagout Training: Workers must be trained on lockout/tagout procedures to prevent accidental energization of equipment.
• Ergonomics Training: Workers must be trained on proper lifting techniques to prevent musculoskeletal injuries.

8. Monitoring and Review

Review Frequency: Annually, or after any incident or significant change in procedures

Monitoring Type	Frequency	Responsible Party	Description
Regular Inspection	Monthly	Safety Officer	Regularly inspect fall protection equipment (harnesses, lanyards) for damage or wear.
Performance Indicator	Quarterly	Occupational Hygienist	Monitor air quality in work areas where dust or fumes are present.
Audit	Annually	Safety Manager	Conduct periodic audits of lockout/tagout procedures to ensure compliance.

9. Special Circumstances

• Adverse weather conditions (e.g., high winds, rain) can increase the risk of falls from height.
• Night work can reduce visibility and increase the risk of accidents.
• Lone work increases the time before assistance can arrive in the event of an incident.
