Working with wet concrete and screed

1

 When skin is in contact with fresh concrete or screed , skin irritations are likely to occur due to the alkaline nature of cement.
   

2

If fresh concrete or screed does come into contact with skin or eyes it may cause serious burns or ulceration. Potential effects range from dry skin, irritant contact dermatitis, to -

in the case of prolonged exposure - severe burns. The eyes are particularly vulnerable and damage will increase with contact time. Strong alkaline solutions put in contact with the skin will damage nerve endings first before damaging the skin, and therefore chemical burns can develop without pain felt at the time.

   

3

 Unlike heat burns, cement burns might not be felt until some time after contact with fresh concrete, so there might be no warning of damage occurring.
   

4

 Take care to prevent fresh concrete from entering boots, gloves or protective clothing and use working methods which do not require people to kneel in fresh concrete.
   

5

 Risk of burns and dermatitis are increased if wet concrete or screed are allowed to keep rubbing against skin, in boots, gloves or clothing.
   

6

 If cement or concrete enters the eyes, immediately wash out thoroughly with clean water and seek medical attention immediately.
   

7

 Wash wet concrete off the skin immediately. Barrier creams may be used to supplement protective clothing but are not an alternative means of protection.
   

8

 Wash all clothing that has been contaminated with wet concrete or screed before use.
   

9

 Any cuts or abrasions to skin should be suitably protected before working with fresh concrete or screed.
   
   
 

Transporting and moving wet concrete and screed
   

1

 Mixed concrete is very heavy. A standard wheelbarrow can weigh up to 110kg and therefore moving such a load can cause physical injury if done incorrectly.
   

2

 It is essential that you carry out all movement of concrete following current health and safety regulations so as to ensure that you move, compact and finish the work without straining yourself.
   

3

 When pushing wheelbarrows ensure that all pathways are clear and constructed ramps are suitable for the movement of heavy loads.
   
   
 

Always wear protective clothing when working with concrete and screed
   
A Protect hands with waterproof gloves at all times.
B When standing or working in concrete or screed wear Wellington boots.
C Cover as much skin as possible, especially wear long trousers and long sleeved shirt.
D If kneeling in concrete or screed always wear knee pads.
E Always wear goggles if there is any chance of splashes entering the eyes.
