TYPES OF ACCIDENTS

Unsafe working conditions

Falling from heights

Falling objects

Electrocutions and Power tool accidents

Excessive noise / Vibrating tool hazards

Scaffolding Accidents

Stepladder misuse

Construction vehicle accidents

An unsafe condition is “a condition in which the physical layout of the workplace or work locations, the status of tools, equipment, and/or material are in violation of contemporary safety standards”.

UNSAFE WORKING CONDITION

FALLING FROM HEIGHTS

• Falling accidents typically occur when a worker steps to or backwards an open-sided floor or slab and focuses on the work. Slips, trips and low falls are the most common forms, and usually cause minor injuries (e.g. musculoskeletal disorders, puncture wounds, etc.). By contrast, fatal accidents can be caused by falls from height, and in most cases workers suffer from head or shoulder wounds. Lack of opening protections, inadequate edge protections, may lead to potential falling hazards.

FALLING OBJECTS

• In the site when an object is dropped onto you from above without any warning or the ability on your part to move out of the way causing an injury to you which makes it impossible for you to continue working. Injuries could vary from minor cuts and bruises to more serious crush injuries and head and brain injuries.

ELECTROCUTIONS AND POWER TOOL ACCIDENTS

• Electrocutions can be caused by body contact with power cables, cable strikes on underground utilities, or defective of ground-fault protection. Power tool accidents, such as nail gun injuries, are usually caused by inappropriate use or inadequate eye protection. Furthermore, improper guards in place on power tool management may lead to more severe injuries.

EXCESSIVE NOISE / VIBRATION TOOL HAZARDS

• Noise and vibrating tools are also a cause for concern whilst working in the construction industry as excessive noise from power tools can cause hearing loss or problems such as tinnitus (ringing in the ears). The vibration from power tools can cause nerve and tendon damage to the hands, arms and wrists which if experienced can be extremely debilitating with reduction and sometimes total loss of grip strength.

SCAFFOLDING ACCIDENTS

• Scaffolding accidents cause large numbers of deaths and injuries every year. Most accidents are caused by scaffold equipment failure, inadequate scaffolding safety training, lack of personal fall protective systems, or improper scaffolding equipment operation. In addition, materials and tools falling off scaffolding may also cause injuries.

STEPLADDER MISUSE

• The majority of falls in construction accidents are due to stepladder misuse or failures. Ladder injuries include loss of balance, improperly ladder setting up, loss of balance, and exceeding the ladder weight capacity, etc.

CONSTRUCTION VEHICLE ACCIDENTS

• Large construction equipment (e.g. cranes, forklifts, dump trucks, road graders and concrete mixtures, etc.) may become potential dangers on a construction site. Due to their weight and size, workers and drivers can be seriously injured or killed in an accident. In some cases, drivers may not have competent driving skills, or their visibility may be limited due to site constraints.
