Activity Hazard Analysis (AHA)

Activity Title: Drilling with 8250 LS Sonic Drill Rig on a Shoulder of I-95 Prepared by: Vlad (e-SafetyPro, [email protected]) ---

Purpose

The purpose of this Activity Hazard Analysis (AHA) is to identify potential hazards associated with the operation of a 8250 LS Sonic Drill Rig on the shoulder of I-95 in New Jersey and to establish safety controls to mitigate risks to workers, traffic, and the surrounding environment.

Project-Wide Hazards & Controls

Hazards:

1. Traffic Hazards: Proximity to moving vehicles on I-95 can lead to accidents. 2. Noise Exposure: Operation of the drill rig creates high noise levels. 3. Site Conditions: Uneven terrain and potential for ground instability. 4. Equipment Hazards: Risks associated with operating heavy machinery. 5. Environmental Hazards: Potential for spills or leaks affecting soil and water.

Controls:

1. Traffic Control Plan: Implement a traffic control plan with signage and barriers per DOT guidelines. 2. Hearing Protection: Provide earplugs or earmuffs to mitigate noise exposure. 3. Site Assessment: Conduct a pre-drilling site assessment to identify and address site conditions. 4. Equipment Training: Ensure operators are certified and trained in safe operation of the drill rig. 5. Spill Containment: Have spill kits readily available on-site to address any environmental incidents. ---

Step-by-Step Hazards & Controls

Major Steps:

1. Set Up Drill Rig - Hazards: Equipment malfunction, uneven terrain. - Controls: Conduct pre-use inspections; level the rig on stable ground. 2. Establish Traffic Control - Hazards: Inadequate protection from traffic. - Controls: Set up cones, signage, and barriers; deploy flaggers as needed. 3. Drill Operation - Hazards: Noise exposure, mechanical hazards. - Controls: Use hearing protection; ensure all personnel maintain a safe distance from the drill rig. 4. Post-Drilling Procedures - Hazards: Ground instability; potential for equipment accidents during breakdown. - Controls: Secure site; conduct a post-operation inspection of the site and equipment. 5. Site Restoration - Hazards: Environmental impact, slips, and falls. - Controls: Follow environmental guidelines for restoration; ensure the area is clean and safe. ---

Notes/Recommendations

• Conduct a daily safety briefing before work begins to review hazards and controls.
• Ensure that all equipment is maintained and inspected regularly to prevent malfunctions.
• Engage with local authorities regarding traffic management and ensure they are aware of the project schedule.
• Monitor weather conditions as they may affect site safety and drilling operations. This AHA should be reviewed and updated as conditions change or as new hazards are identified. All personnel must be familiar with this AHA and adhere to the outlined safety measures.
