3) Safety Awareness :

The underlying cause accidents, injuries and incidents is invariably a lack of Safety Awareness linked with

unsafe behaviour.

Safety awareness is;

- Being alert to what you are doing and what is going on around you.

- Identifying potential hazards and taking the appropriate precautions to minimise and eradicate the risk.

- Something everyone has to learn if he or she is to stay injury free

- Part of every employees job, Everyone should carry out a Self Assessment and use Total Observation to;

- Think about how you have done similar jobs in the past.

- Think about how you are doing or planning to do the job now.

- Compare the two operations with how the job should be done safely.

- Look at everything that is taking place around you and anything that could pose a hazard to you.

- Look above, below, behind and inside. Use the questioning Attitude to ask.

- Have any people been injured doing this particular job ?

- What injuries could occur if the unexpected happens ?

- On, what I am doing will it affect other people ?

- Do I have the authority, have I been trained, am I capable of doing the job ?

- Do I need to wear or am I wearing the correct Personnel Protective Equipment ?

Eye Injuries :

- There have been a few entries in the accident books that relate to injuries to the eyes.

- Most of these injuries could have been avoided if the operatives had been wearing

goggles as proposed to safety glasses

- With immediate effect, Sub-Contractor Management insists that all personnel working inside the Process Plant wear

Safety Goggles /Glass at all times.

- If the housekeeping at the worksite is poor or if there is a long standing dust hazardoperatives are encouraged to report the matter to their supervisor.

6.8 Personnel Protective Equipment (PPE) :

The minimum standard of Personnel Protective Equipment is

- Head Projection,

The Process Plant is a designated Hard Hat site so safety helmets must be worn in all

the plant area. You must change your helmet if it is damaged in any way.

- Body Protection.

Protective clothing that is the right size, suitable for the job and properly maintained

must be worn all time at the Process Plant. Overalls must be made from 100% cotton.

- Safety FootwearSafety Footwear must be worn at all times in al l plant areas. The most common type of safety footwear is the safety

boot or shoe. It is recommended that they are fitted with at least a 200 joule toe-cap.

- Eye and face Protection (Note : eye injuries)The wearing of eye protection is mandatory on all Process areas, workshops, Fabrication

yards and fire training ground. Eye protection is also recommended on roadways adjacent to process units.

Face shields or visors and/or specialist equipment (such as air-fed welding hoods) must be worn depending on the

application or as dictated by Client Operation/Work Permit..

AES-VCM

7/34

- Hearing Protection

Adequate hearing protection must be worn at all times in the designated high noise areas.

Audits are finding lots of people not wearing ear defends in the high noise areas. There are two types of ear defenders

available for use i.e muffs fitted to the helmet and ear plugs which fit inside the ear canal.

- Hand Protection

Personnel working on site are likely to be expose to a number of hazards i.e. thermal, mechanical, chemical and vibration.

Where there is a risk of contact with one or more of these hazards then the appropriate protective gloves must be worn.

- Good Housekeeping.

Poor housekeeping and untidy working is a MAJOR source of accidents and injuries.

Sub-contractor is expected to clean up and debris created and after every job. Stop work and tidy up if the work area

is becoming cluttered and ensure that you take time out at the end of every work period to do some housekeeping.

Persistent untidy workers cannot be tolerated.

Housekeeping audits are being conducted on a daily basis by both Sub-contractor and CLIENT managementand the auditors will be looking at the following area.

- Hose and cable discipline i.e. trailing hoses and cables that do not restrict access egress, passage ways or roadways.

- Oil and process spill. Any liquid should be contained in dams or soaked up with proprietary absorbent materials suchas ”Spillsorb or soak-up” before disposal in the approved manner. Solids and dusts should be either dampened

down or vacuumed up as soon as possible.

- Insulation and scaffolding debris. This material should be removed as soon as possible and disposed of in the approved

area.

- Engineering and General Debris. To be removed as soon as possible and disposed of the approved area, meanwhile, it

must be stored in a tidy manner.

- Elevated platforms, stairways, and access ways free from debris and/or obstruction. Tools and equipment must be positioned

so that they cannot be fall onto people working below.
