Safe Work Procedure: Grounding

Document Number: [SWP-NUMBER] Revision Date: [DATE] Next Review Date: [NEXT REVIEW DATE] Department: [DEPARTMENT NAME]

1. Scope

This Safe Work Procedure (SWP) outlines the necessary steps and safety precautions for performing grounding tasks. It applies to all workers involved in grounding activities and aims to minimize the risks associated with electrical hazards and ensure a safe working environment.

2. Definitions

Grounding: A process of creating a low-resistance path to the earth to safely dissipate electrical fault currents.

3. Responsibilities

3.1 Supervisors

Ensure all workers are properly trained and competent in grounding procedures.
Provide the necessary equipment and PPE for safe grounding work.
Monitor work practices to ensure compliance with this SWP.

3.2 Workers

Follow all steps outlined in this SWP.
Use required PPE and equipment correctly.
Report any hazards or incidents to the supervisor immediately.

3.3 Health and Safety Representative

Assist in the development and review of this SWP.
Promote safety awareness and best practices related to grounding.

4. Potential Hazards and Risks

Hazard	Risk	Control Measures
Electrical shock	Injury or death	Ensure proper grounding techniques are used. Verify circuits are de-energized before grounding.
Arc flash	Burns, eye damage	Wear appropriate PPE, including arc-rated clothing and face shield. Maintain safe distances from potential arc flash zones.
Improper grounding	Equipment damage, electrical hazards	Use correct grounding equipment and methods. Inspect grounding equipment for damage before use.
Dust inhalation	Respiratory irritation, silicosis	Use approved respirator or other dust mask when using the product to avoid or minimize exposure to dust [1].
Skin contact	Skin irritation, burns	Wear protective gloves/protective clothing [1].
Eye contact	Serious eye damage	Wear eye protection/face protection [1].

5. Personal Protective Equipment (PPE)

Always use proper PPE to minimize exposure to hazards.

Safety Glasses with Side Shields: Protect eyes from dust and debris 6, 9, 11, 14.
Gloves: Protect hands from abrasion and potential skin irritation 6, 7, 11.
Long Sleeve Shirt and Long Pants: Provide a barrier against skin abrasions and irritants [2].
Respiratory Protection: Use a NIOSH-approved dust mask or respirator where dust or fumes are generated and may exceed recognized allowable exposure levels 6, 9, 14.

Inspect PPE before each use to ensure it is in good condition. Replace damaged or worn PPE immediately.

6. Equipment and Tools

Always use proper equipment and tools for grounding tasks.

Grounding Cables: Used to create a low-resistance path to ground.
Ground Clamps: Used to securely connect grounding cables to equipment and grounding points.
Voltage Tester: Used to verify that circuits are de-energized before grounding.

Inspect all equipment and tools before each use to ensure they are in good working condition. Remove any damaged equipment from service.

7. Pre-Job Requirements

7.1 Training and Competency

Workers must be trained and competent in grounding procedures, including the proper use of equipment and PPE.

7.2 Pre-Job Briefing

Conduct a pre-job briefing to discuss the scope of work, potential hazards, and safety precautions. Ensure all workers understand the SWP and their responsibilities.

7.3 Work Area Preparation

Ensure the work area is clear of obstructions and hazards. Provide adequate lighting and ventilation.

8. Safe Work Procedure Steps

Step 1: Hazard Assessment

Detailed description of step 1: Before starting any grounding work, conduct a thorough hazard assessment to identify potential risks.

Sub-step 1.1: Identify all potential electrical hazards in the work area.
Sub-step 1.2: Assess the risk of electrical shock, arc flash, and other hazards.
Sub-step 1.3: Determine the appropriate control measures to mitigate identified risks.

Safety considerations for this step: Ensure all hazards are properly identified and controlled before proceeding with the work.

Step 2: De-energize and Isolate

Detailed description of step 2: Before grounding any equipment, ensure that it is de-energized and isolated from all power sources.

Sub-step 2.1: Disconnect the equipment from its power source.
Sub-step 2.2: Lockout and tagout the power source to prevent accidental re-energization.
Sub-step 2.3: Verify that the equipment is de-energized using a voltage tester.

Safety considerations for this step: Double-check that the equipment is de-energized before proceeding. Use a voltage tester to confirm.

Step 3: Install Grounding Equipment

Detailed description of step 3: Install grounding cables and clamps to create a low-resistance path to ground.

Sub-step 3.1: Connect one end of the grounding cable to the equipment to be grounded.
Sub-step 3.2: Connect the other end of the grounding cable to a verified grounding point.
Sub-step 3.3: Ensure that all connections are tight and secure.

Safety considerations for this step: Use properly rated grounding cables and clamps. Ensure grounding points are verified for effectiveness.

9. Precautions and Safety Measures

Electrical Safety: Always treat electrical circuits as live until proven otherwise.
PPE Use: Wear all required PPE, including safety glasses, gloves, and appropriate clothing 6, 7, 9, 11, 14.
Equipment Inspection: Inspect all grounding equipment before use to ensure it is in good working condition.
Hazard Communication: Communicate potential hazards to all workers in the area.
Emergency Preparedness: Know the location of emergency equipment and procedures.

10. Emergency Procedures

10.1 General Emergency Response

In the event of an emergency, immediately stop work and assess the situation. Evacuate the area if necessary and follow established emergency response procedures.

10.2 Specific Emergency Scenarios

Electrical Shock: Immediately disconnect the power source if safe to do so. Provide first aid and call for medical assistance.
Fire: Activate the fire alarm and evacuate the area. Use appropriate fire extinguishing equipment to put out the fire 5, 6, 9, 11, 12, 13, 14, 16.
Injury: Provide first aid and call for medical assistance.

10.3 Emergency Contact Information

Emergency Services: 911
[Company Safety Officer]: [PHONE NUMBER]
[Local Hospital]: [PHONE NUMBER]

11. Incident Reporting and Investigation

Report all incidents, near-misses, and hazards to the supervisor immediately. Participate in the investigation to determine the root cause and implement corrective actions.
