Site 10 specific construction hazards and rate them using a 3x3 Risk Matrix for risk analysis. Give control measure(s) for. (just give the specific work activity, hazards, existing controls if any, and control measures)

Details:

Likelihood

1. unlikely - occurs during accident breakdown or emergency situation

2. likely - occurs during regular scheduled practice i.e. monthly or yearly maintenance

3. almost - occurs during normal everyday practice.

Severity

1. Minor - superficial injuries, nuisance, irritation, ill health leading to temporary discomfort.

2. Major - Lacerations, burns, fractures deafness, dermatitis, ill-health leading to permanent minor disability.

3. catastrophic - Amputations, Major fractures, Fatal injuries, severe life shortening diseases

3x3 risk matrix for analysis

	severity
likelihood	minor 1	major 2	catastrophic 3
almost 3	M(3)	M(6)	H(9)
likely 2	L(2)	M(4)	M(6)
unlikely 1	L(1)	L(2)	L(3)

High risk: STOP/investigate the process and implement controls immediately

Medium risk: keep the process going; however, a control plan must be developed and should be implemented as soon as possible

Low risk: keep the process going, but monitor regularly. A control plan should also be investigated

Hierarchy of controls:

Elimination

Substitution

Engineering Controls

Administrative Controls

Personal Protective Equipment

Work activities:

assembling of formworks and erection of scaffolding on high-rise buildings

10 x 32 sqm footing foundation excavation

Assembling of steel structures such as flange beams through welding

painting of walls on the second and third floor of a 3 storeys building

Pouring of floor slab at second or upper floors

Erection of steel columns

Installation of steel trusses and roofing

Piledriving of reinforced concrete piles in bridge construction

Launching of girders, and placing it on bridge abutment in bridge construction

installation of glass wall in high rise buildings

breaking and dismantling of damaged road and pavement using hydraulic breaker attached to backhoe operated and pneumatic jackhammers operated by operators/workers

erection of transmission towers (power distribution lines, telecommunication lines)
