1. Scope

This procedure covers the safe conduct of blasting operations, including preparation, execution, and post-blast activities. It applies to all personnel involved in blasting activities and is designed to ensure safety and compliance with regulatory requirements.

This procedure is applicable to all work environments where blasting is conducted, including construction sites, mining operations, and demolition projects.

Related procedures and documents include the Blasting Permit, Seismograph Reports, and the Blaster's Log.

2. Definitions

Blaster
A person qualified and authorized to conduct blasting operations.

Seismograph
An instrument used to measure and record the intensity of ground vibrations caused by blasting.

Stemming
Material used to confine explosives in a borehole.

3. Responsibilities

3.1 Supervisors

• Ensure all blasting operations comply with safety regulations.
• Verify that all personnel involved in blasting are trained and authorized.
• Conduct pre-blast safety meetings and ensure all safety measures are in place.

3.2 Workers

• Follow all safety instructions and procedures during blasting operations.
• Use personal protective equipment (PPE) as required.
• Report any unsafe conditions or incidents immediately.

3.3 Health and Safety Representative

• Monitor compliance with safety procedures during blasting operations.
• Conduct regular safety audits and inspections.

4. Potential Hazards and Risks

Hazard	Risk	Control Measures
Explosive detonation	Injury or death	Ensure safe distance and use of protective barriers [1]
Flying debris	Injury	Use blasting mats and ensure all personnel are at a safe distance [2]
Misfire	Delayed detonation risk	Follow misfire handling procedures [3]

5. Personal Protective Equipment (PPE)

Proper PPE is essential to protect workers from hazards associated with blasting operations.

• Hard Hat - Protects against head injuries from flying debris.
• Safety Glasses - Protects eyes from dust and debris.
• Hearing Protection - Protects against noise from explosions.
• Safety Boots - Protects feet from heavy objects and debris.
• Respiratory Protection - Required when working in dusty environments [4].

Inspect PPE before use and replace any damaged equipment.

6. Equipment and Tools

Using the correct equipment and tools is crucial for safe blasting operations.

• Blasting Machine - Used for initiating blasts safely [5].
• Seismograph - Monitors ground vibrations [6].
• Non-sparking Tools - Used for handling explosives to prevent accidental detonation [7].
• Blasting Mats - Used to control debris [2].
• Warning Signs - Indicate blast areas and ensure unauthorized personnel are kept away [8].

Inspect and maintain equipment regularly to ensure proper functioning.

7. Pre-Job Requirements

7.1 Training and Competency

All personnel involved in blasting must be trained and certified in blasting operations.

7.2 Pre-Job Briefing

Conduct a safety briefing covering the blasting plan, potential hazards, and emergency procedures.

7.3 Work Area Preparation

Ensure the blast area is clear of unauthorized personnel and equipment. Set up warning signs and barriers.

8. Safe Work Procedure Steps

Step 1: Preparation

• Obtain necessary permits and approvals.
• Conduct a site survey to identify potential hazards.
• Set up seismograph if required [6].

Step 2: Loading

• Load explosives into boreholes using non-sparking tools [7].
• Ensure all personnel are at a safe distance during loading [8].

Step 3: Detonation

• Ensure all personnel are in safe locations.
• Initiate the blast using a blasting machine [5].
• Monitor the blast area for any misfires or hazards.

9. Precautions and Safety Measures

• Maintain Safe Distances - Ensure all personnel are at a safe distance during blasting.
• Use Warning Signals - Use audible signals to warn of impending blasts [6].
• Control Access - Restrict access to the blast area to authorized personnel only [1].
• Monitor Weather Conditions - Avoid blasting in adverse weather conditions.
• Inspect Equipment - Regularly inspect all blasting equipment and PPE.

10. Emergency Procedures

10.1 General Emergency Response

In case of an emergency, evacuate the area and contact emergency services.

10.2 Specific Emergency Scenarios

• Misfire - Follow misfire handling procedures and ensure the area is safe before resuming work [3].
• Injury - Provide first aid and contact emergency services immediately.

10.3 Emergency Contact Information
