CONSTRUCTION SAFETY

Juan Nunez Carp 11

In construction safety there is a “Focus Four” that contributes to the greatest number of preventable fatalities in the construction industry. Fall Hazards require a fall protection system to protect workers from falling from elavation or ground level to lower levels,falls through exisiting floor or roof openings,floor and roof collapses and jump from structures and equipment.

Fall Hazards:

The Focus Four are Fall Hazards, Electrocution, Struck By Hazards, and Caught In Between Hazards Fall Hazards can be protected by Safety Monitoring systems, Safety Net Systems, Personal Fall Arrest System and Guardrails

Electrocution Hazards in Construction Major types of electrocution hazards are:

• Contact with power

lines

• Contact with

energized sources

• Improper use and

flexible cords Dangers of being struck by electric components

• High voltage from

120v to 750,000v of electricity Protecting yourself from electrocution hazards:

• Maintaining and marking safe distance

from overhead and buried power

• Using Non-Conductive Equipment
• Ensuring lines are de-energized
• Using ground fault interceptors
• Using power tools and equipment as

intended

• Following lockout/tagout procedures

Struck-By Hazards in Construction

Struck-By flying objects hazards are thrown, hurled or propelled through space and strike workers Examples include:

• Piece of material separating from

equipment

• Objects ejected from power-actuated

equipment such as nail guns and fasteners

• Compressed air from tools

Protecting yourself from struck-by hazards:

• Staying away from or being alert when around heavy

equipment such as cranes and excavators

• Practicing vehicle safety around roadways, including

wearing high visibility clothing and using traffic signs and barriers.

Caught In Between Hazards in Construction

Examples of caught in between or caught in hazards:

• Cave ins during trenching
• Clothing caught in equipment
• Crushed between semi-trailer and

wall

• Crushed between truck and

forklift Preventing Caught In Between Hazards:

• Only use properly guarded machinery and

equipment

• Safeguard any moving parts
• Do not wear loose clothing that can get caught
• Make sure all machinery is sufficiently supported,

secured and safe

Scaffolding in Construction It is estimated that 2.3 million construction workers frequently work on scaffolds, which is 65% of the construction industry. Protecting those workers from potential hazards could save us 50 deaths,4,500 injuries and $90 million dollars a year. Falling from heights because of improper fall arrest systems were used causes a lot of injuries in scaffolding Fall arrest systmes like a harnest can help you a lot from falling from the extreme heights that you can be exposed to from scaffolding

Excavation in Construction Risks in Excavation:

• Falling into pit
• Suffocation

/breathlessness, Buried

• Contact with buried

electric cable, Gas / Oil Pipelines

• Movement of

vehicles / equipment close to the edge of cut. Preventions:

• Provide guard rails /

barricade with warning signal, provide minimum two entries

• Employ suitable size
• f shoring and

strutting if required

• Obtain permission

from competent authorities prior to excavation if needed. Different types of hazards are associated with excavation of soil. for instance, failure of soils at sides of trenches and pits, movement of buildings due excavations at its vicinity, falling workers into pits, buried workers due to collapse of earth, cave- in which may cause suffocations of labors etc. These hazards should be identified, and preventive measures should be taken to avoid any accident at construction sites.

Types Of Personal Protective Equipment

• Light latex, vinyl or

nitrile gloves

• Flame resistant (e.g.

Nomex or other flame-resistant cotton — resists ignition)

• Barrier

(predominantly polyester — offers splash protection, not flame resistant)

• Full-face and half-

faced respirators

• Disposable and

reusable earplugs

• Hearing band
• Impact goggles
• Face shields

Health and safety is a very important factor not

• nly in human terms but

also at occupational point of view. Health and safety at any workplace helps to reduce or even avoid workers’ pain, injury and other sufferings. Health and safety of the workers guarantee the Company’s ‘brand image’ and ‘brand value’. In this way, the motivation and the commitment of employees to the business is increased, company enables to meet customer expectations. Health and safety problems might lead to irreversible

• consequences. The business deals with disruption, damage of

the machinery, insurance costs, claims for damages and loss of confidence in management may lead to collapse or even

• bankruptcy. For the individual, there are the costs of care, loss of

earnings etc. The research shows that investing in safety and health leads to better company performance Review in Construction Safety
