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.

 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 area.

Use only designated roads for delivery of concrete.

 Ensure to wear suitable respiratory 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

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.:  blockage

 change in supply

 poor mix or delays in the pour  Ensure delivery hose is not damaged

prior to pour

 Control T-bar at end of hose  Be aware of potential for blow back

in the line

 Ensure appropriate edge protection  Ensure connecting pipes are

adequately secured

 Ensure brackets are positioned close

6 Work during extreme weather/ climate conditions.

 Over exposure to heat IMCO personnel can cause heat cramps, heat exhaustion or heat stroke

4 x 4 = 16 • Become acclimated to the heat gradually before working in hot temperatures for a long time; • Ensure 100% availability of cold

water and always drink plenty of cool water;

• Wear hats and sunglasses to help stay cool;

• Take frequent breaks in a cool place, if possible;

• Wear loose clothing that allows the skin to breathe, such as cotton; • Protect your skin from the sun. Keep

as much of it covered with clothing as possible. Wearing long-sleeved shirts will help;
