 Risk Assessment for High Mast and Street Light Pole Installation

Here’s a Risk Assessment for High Mast and Street Light Pole Installation, covering common hazards, risk levels, and control measures — suitable for projects in construction, municipal, or industrial sites.

 

📝 Risk Assessment: High Mast & Street Light Pole Installation

Activity	Hazard	Risk	Control Measures
1. Site Preparation	Underground services (cables, pipelines)	Electric shock, explosion	- Conduct utility scan (using cable locator) - Obtain NOC from utility providers - Follow approved drawings
	Uneven ground / debris	Slips, trips, falls	- Clear site before work - Use barriers and warning signs
2. Excavation for Pole Foundation	Collapse of excavation	Injury from falling soil	- Shoring or trench box - Safe access & egress - Supervision during digging
	Manual handling	Back injury	- Use mechanical equipment - Team lifting for heavy loads
3. Pole Handling & Lifting	Falling pole during lifting	Fatal injury / damage	- Use certified crane - Trained riggers - Lifting plan and signalman
	Poor rigging/lifting gear failure	Equipment damage, injury	- Pre-use inspection of slings and shackles - Only certified rigging gear
4. Erection of Pole	Pole instability	Tipping over	- Ensure correct foundation size and curing - Anchor bolts torqued properly
	Working at height	Fall hazard	- Use safety harness and lifeline - Proper scaffolding or man lift
5. Electrical Connection	Live wire contact	Electric shock, burns	- Ensure power is isolated (LOTO) - Use voltage tester - Only qualified electricians
	Faulty wiring / poor termination	Fire risk, equipment damage	- Follow wiring standards - Double-check connections - Use certified materials
6. Roadside Work	Moving vehicles	Struck-by injury	- Use traffic diversion plan - High-visibility PPE - Signboards and cones
7. Testing & Commissioning	Equipment failure	Shock, short circuit	- Test using insulated tools - Wear rubber gloves/shoes - Follow standard procedures

🎯 General Control Measures

• Daily Toolbox Talk
• Use of PPE (helmet, gloves, safety boots, reflective vest, safety harness)
• Method Statement & Permit to Work (PTW) in place
• Supervision by competent personnel
• Emergency response plan available onsite

All relevant controls from above, plus:

• Ensure appropriate lighting levels are provided for all tasks, including inspections and emergencies.

• Regularly inspect and maintain all electrical equipment, including transformers, generators, and UPS units, as per manufacturer's recommendations and Saudi standards (SEC).

• Implement a robust LOTO (Lockout/Tagout) program for all maintenance activities.

• Ensure proper ventilation for generators and UPS batteries.

• Clear access routes to all equipment for operation and maintenance.

• Conduct regular drills for power outages and emergency generator/UPS activation.

• Maintain comprehensive single line diagrams (SLDs) and equipment layouts.

• For Power Factor Correction, Short Circuit, and Voltage Drop Calculations: These are design functions. Ensure they are performed by competent, certified electrical engineers in accordance with latest Saudi Building Code (SBC 401), SEC standards, and relevant international codes (e.g., IEC, IEEE). All calculations must be documented, reviewed, and approved before implementation.

• Implement Power Quality Monitoring systems to ensure stable voltage and frequency and to identify potential issues before they cause failures.

• Ensure coordination of protective devices (circuit breakers, fuses) based on short circuit calculations to isolate faults quickly.
