Introduction:There are too many line items in life which you cannot calculate. Gravity is one among them. When you lose your balance and fall that’s called as Gravity at work. Many people life at risk got injured or died due to fall from height during the job. Fall from height results in serious injury than any other accidents in the industry. People suffer from broken bones, spinal injuries, paralysis and few more after the fall from height.

Introduction – Ladders are a great resource to help workers access materials or work areas that are out of reach. Additionally, ladder accidents are one of the leading causes of occupational injuries and fatalities.

Introduction:Fall protection is the standby system provided for aemployee who could lose his or her equilibrium at height, in order to control or eradicatedamage potential. The fall protection is required to restraint or arrest the fall from heights. The person falling from height may lose balance or grip or may slip, or may trip or may misstep at any point of time. Fallen from height or elevated place results in serious injuries and it could be the most serious injury than any other accident in the industries.

Anytime work is being performed overhead where others may be working or walking below, regardless if work is being performed from a scaffold, platform or ladder. Steps shall be taken to prevent hazards associated with falling objects.

• Toe boards shall be used on working platforms and scaffolds over 6 feet (1.8m) in height.
• Materials shall not be allowed to accumulate next to the edge of the work platform without a means to prevent objects from falling into the area below.
• Access to the lower area shall be restricted to protect workers or pedestrians in the area.
• Tools and materials shall be secured either through tethering or other means if they may be dropped to the lower level.

For more than 2 metres, it is commonly defined as high level fall in which most injuries are resulted from. However, there is an increasing trend that there has been similar number of injuries from low level falls (i.e. less than 2 metres) and from high level falls. As such, some countries have deleted the “2 metre rule” as the definition of falling at height. Instead, it is newly defined as working at a place from which a person could be injured by falling from it, regardless of whether it is above, at or below ground level without stating the level of fall.

The main principle of safety helmet is to protect workers against impact by falling objects or struck by swinging object by energy absorption. Upon hitting by an object, the helmet dissipates some of the energy in the following mechanisms:

(i) Stretching of harness inside the helmet;
(ii) Partial damage of outer shell of helmet.

The remaining energy is then evenly spread around the head to reduce the hitting stress on worker’s head.
