CHAPTER 3
SAFETY
3.1. Construction Site Safety
Construction site safety is an aspect of construction-related activities concerned with
protecting construction site workers and others from death, injury, disease or other health-
related risks. Construction is an often hazardous, predominantly land- based activity where
site worker may be expected to various risks, some of which remain unrecognized. Site risks
can include working at height, moving machinery (vehicles, cranes, etc.) and materials,
power tools and electrical equipment, hazardous substances, plus the effects of excessive
noise, dust and vibration. The leading causes of construction site fatalities are falls,
electrocutions, crush injuries, and caught- between injuries.
3.2. Electrical Safety
Electrical safety is paramount on construction sites due to the numerous hazards
associated with the use of electricity. Unsafe practices can lead to severe injuries, fatalities,
and property damage. This chapter explores the fundamental aspects of electrical safety,
emphasizing the importance of proper training, equipment, and procedural protocols to
prevent accidents and ensure a safe working environment.
3.2.1. Important of Electrical Safety
Working around electricity can be very safe on the job site when workers properly
identify and control hazards. But, inadequate training, lack of experience, and failure to
recognize potential hazards could result in electric shock or death. The construction industry
is most in danger from electrical hazards, accounting for 52% of all electrical fatalities in the
US workplace. Most of these incidents and fatalities were caused by direct worker contact
with overhead power lines and contact with machines, tools, and hand-carried metallic
objects. This article provides a closer look at some common electrical hazards in the
workplace and how to be safe around them.
3.2.2. Risk of Electrical Safety
Engineers, electricians, and overhead line workers, both contractors and
subcontractors are at the top of the list of professionals who are most exposed to electrical
hazards. Common tasks that put these workers at risk include electrical installation and
repairs, testing of fixtures and equipment, and inspection and maintenance activities.
However, people who are indirectly working with electricity like office workers are also
exposed to electrical hazards.
3.2.3. Type of Electrical Hazards
Many types of electrical hazards are-
• Electric Shock: Occurs when a person comes into contact with a live electrical
component, leading to potential injury or death.
• Arc Flash: A sudden release of electrical energy through the air when a high-voltage
gap exists and there is a breakdown between conductors.
• Arc Blast: The explosion resulting from an arc flash, causing high-pressure waves,
intense heat, and projectiles.
• Fire: Electrical malfunctions can ignite fires, posing significant risks to life and
property.
• Explosions: In certain conditions, electrical sparks can ignite flammable gases or dust,
leading to explosions.
3.2.4. Common Causes of Electrical Accidents
There are five common causes of electrical accidents in construction sites. They are
following –
• Improper Wiring: Faulty or poorly installed wiring can lead to short circuits and
overheating.
• Damaged Equipment: Worn-out or damaged tools and equipment can expose live
wires.
• Overloaded Circuits: Exceeding the capacity of electrical circuits can cause
overheating and fires.
• Lack of Grounding: Without proper grounding, electrical systems can become
unstable and hazardous.
17
• Inadequate Training: Workers lacking proper training may not recognize electrical
hazards or know how to mitigate them.
3.3. Safety Equipment
Electrical safety equipment is specialized personal protective equipment designed to
protect workers from general and specific electrical hazards. Generally, the most used
electrical safety equipment is insulated tools and PPEs like insulated gloves, mats, and
ladders. Electrical safety equipment should also be used when doing specific types of
electrical testing, repair work, installation, or maintenance such as arc flash and customized
earthing and short-circuiting, among others. And for an extra layer of safety, it helps to verify
if your electrical equipment is certified by a nationally recognized testing laboratory.
3.3.1. Damaged Tools and Equipment
Exposure to damaged electrical tools and equipment can be very dangerous. Do not fix
anything unless you are qualified to do so. Thoroughly check for cracks, cuts, or abrasions on
cables, wires, and cords. In case of any defects, have them repaired or replaced. Lock out Tag
out (LOTO) procedures should be performed at all times before commencing electrical
maintenance and repairs. LOTO procedures are there to protect all workers on a worksite.
3.3.2. Inadequate Wiring and Overloaded Circuits
Using wires of inappropriate size for the current can cause overheating and fires to
occur. Use the correct wire suitable for the operation and the electrical load to work on. Use
the correct extension cord designed for heavy-duty use. Also, do not overload an outlet and
use proper circuit breakers. Perform regular fire risk assessments to identify areas at risk of
bad wiring and circuits.
3.4. Inadequate Wiring and Overloaded Circuits
Examples of exposed electrical parts include temporary lighting, open power
distribution units, and detached insulation parts on electrical cords. These hazards can cause
potential shocks and burns. Secure these items with proper guarding mechanisms and always
check for any exposed parts to be repaired immediately.
17
3.4.1. Damaged Insulation
Defective or inadequate insulation is a hazard. Be aware of damaged insulation and
report it immediately. Turn off all power sources before replacing damaged insulation and
never attempt to cover them with electrical tape.
3.4.2. Improper Grounding
The most common OSHA electrical violation is the improper grounding of
equipment. Proper grounding can eliminate unwanted voltage and reduce the risk of
electrocution. Never remove the metallic ground pin as it is responsible for returning
unwanted voltage to the ground.
3.4.3. Wet Conditions
Never operate electrical equipment in wet locations. Water greatly increases the risk
of electrocution especially if the equipment has damaged insulation. Have a qualified
electrician inspect electrical equipment that has gotten wet before energizing it.
3.5. Regulatory Standards and Guidelines
National electrical codes (NEC): The NEC provides guidelines for safe electrical
design, installation, and inspection to protect people and property from electrical hazards.
Personal Protective Equipment (PPE): Proper PPE, such as insulated gloves, safety
glasses, and flame-resistance clothing, is essential to protect workers from electrical hazards.
3.6. Best Practices for Electrical Safety
• Conduct Regular Inspections and Maintenance: Routine inspections and maintenance
of electrical systems and equipment help identify and rectify potential hazards before
they cause accidents.
• Use Ground Fault Circuit Interrupters (GFCIs): GFCIs protect against electric shock
by shutting off the power when they detect a ground fault.
• Implement Lockout/Tagout Procedures: Lockout/Tagout procedures ensure that
electrical equipment is de-energized and cannot be started up during maintenance or
servicing.
17
• Ensure Proper Grounding: All electrical systems should be adequately grounded to
prevent electrical instability and reduce the risk of shock and fire.
• Provide Comprehensive Training: Workers should receive training on electrical
safety, recognizing hazards, and proper emergency response procedures.
• Use Safe Work Practices: Avoid working on live circuits whenever possible. Use
insulated tools, maintain a safe distance from live components, and follow established
safety protocols.
• Implement a Safety Culture: Foster a workplace culture where safety is prioritized.
Encourage reporting of hazards, continuous learning, and adherence to safety
procedures.
3.7. Emergency Response and First Aid
Develop and implement an emergency response plan that includes procedures for
dealing with electrical accidents, such as shocks, burns, and fires.
First Aid for Electrical Injuries:
• Electric Shock: Disconnect the power source immediately and administer CPR if
necessary. Seek medical attention.
• Burns: Cool the burn with running water, cover with a sterile dressing, and avoid
applying ointments. Seek medical attention.
• Arc Flash/Blast Injuries: Move the victim to safety, administer first aid for burns and
other injuries, and seek medical attention.
