2 Mobilization and demobilization

Physical injury from heavy equipment, heavy lifting, pinch point, slip, trips and fall hazards

IMCO Personnel, property damage

4 x 4 = 16 Before transporting the loads to the site, rest assure that the materials are secured and tight with nylon rope for the safe transporting.

Ensure that a driver is having knowledge to the hazard while transporting the materials.

The driver shall not have driving attitude while using the road.

Driver is driving only in the minimum speed limit.

Minimize work personnel in the vicinity of equipment.

Provide ergonomic training, institute good housekeeping procedure.

Keep feet and hands clear of moving/suspended materials and equipment.

Keep a tidy site.

3 Pre-task briefing toolbox talks.

The work force does not understand the pre task briefing therefore does not understand the

potential dangers and control measures to be implemented. Some of the workers could be lacking PPE or using defective PPE.

Ask question regarding the briefing to get feedback from the staff, this ensures full comprehension.

Issue required appropriate PPE and replace PPE that has signs of defect.

PPE must include both hearing protection as well as dust inhalation protection.

4 Set out boundary markers for the work site area.

Heat stress to the labour working on this task.

Markers are not clearly visible creating a risk of others coming into the area.

4 x 3 = 12 Ensure that adequate shaded areas are provided.

Provide proper ventilation and drink plenty of water even if you are not thirst.

Wear loose fitting full length clothing that can breathe.

Ensure that all markers and signage are of a suitable height to be clearly seen and sufficient lighting is placed to identify the area at night.

5 Unloading the ready mix concrete from truck and from concrete pumps

Machine works too close to persons within the same working area.

IMCO personnel 4 x 3 = 12 Ensure that all equipment is having valid QP certificates to work in the vicinity.

Make sure all operators know the safe limitations of their equipment.

working area. Ensure strict control measure to

separate mechanical plant and enforce swing radius area as no go area for any person or vehicle in order to avoid collisions.

Set control measure in place that all fuel transfers take place under strict guidelines. Fuel is only transferred by purpose built fuel delivery tanker.

Ensure all machines and equipments are in good condition.

Regular preventive and corrective maintenance of equipment must be observed.

Drip trays are used to prevent any spillage. Make sure all vehicles are routinely inspected and maintained to reduce the risk of mechanical failure.

In the event that there is ground contamination ensure all contaminated ground is collected and placed into plastic bags, removed to a waste storage container until removed from site to a hazardous waste disposal site.

Deploy equipment delivering materials in such manner that no congestion inside shall happen and no parking anytime in the work

protective equipment such as a P, N or R 95 respirator when fumes from dust can’t be avoided.

Remove person to fresh air. If discomfort persists seek medical advice.

Ensure to wear loose clothing in good condition with collars closed and cuffs buttoned at the wrist.

In case of chemical contact, Remove chemical from skin with waterless hand cleaner

Housekeeping regimes to help keep site clear

Ensure sufficient space around work areas

Ensure there is good access for concrete personnel and equipment

Keep other people not directly involved with concrete pouring clear from area

Ensure that penetrations are secured, identified and covered

Give warning prior to starting or re-commencing the pour

Check hoses for air sources, e.g.:
