Construction Industry: Fatal (Focus-Four) Hazards


Hazards are different in terms of their likelihood of occurrence as well as the severity of consequences they may bring about. Depending upon the risks posed by various kinds of construction hazards, (i) fall, (ii) struck-by, (iii) electrocution and (iv) caught-in (or-between) are the four leading hazards generally encountered in the construction industry. This group of hazards is often referred as the “Focus-Four” and collectively accounts for a huge chunk of accidents, injuries and fatalities at construction worksites. Therefore, dedicated focus should be given to control the risks caused by these four hazards.

(i) Fall Hazard: 

A fall hazard is anything at your work site that could cause you to lose your balance or lose bodily support and result in a fall. Fall hazards are present at most work sites and many workers are exposed to these hazards on a daily basis. Any walking or working surface can be a potential fall hazard.

(ii) Struck-by Hazard:

Struck-by injuries are produced by forcible contact or impact between the injured person and an object or piece of equipment. Having said that, it is important to point out that in construction, struck-by hazards can resemble caught–in or –between hazards. When the impact alone creates the injury, the event is considered as Struck. On the other hand, when the injury is created more as a result of crushing injuries between objects, the event is considered as Caught.

(iii) Electrocution Hazard:

Electrocution results when a person is exposed to a lethal amount of electrical energy. An electrical hazard can be defined as a serious workplace hazard that exposes workers to Burns, Electrocution, Shock, Arc flash, Fire, Explosion, etc. BE SAFE by recognizing, avoiding and protecting against all of these electrical hazards.

(iv) Caught-in (or-between) Hazards:

When the impact alone creates the injury, the event should be recorded as Struck. When the injury is created more as a result of crushing injuries between objects, the event should be recorded as Caught. Caught- in (or -between) hazards in construction cause accidents such as cave-ins (trenching), being pulled into or caught in machinery and equipment (this includes strangulation as the result of clothing caught in running machinery and equipment) or being compressed or crushed between rolling, sliding, or shifting objects.
