| Storage | Cement of all types needs to be kept in a dry moisture free area until used. Normal NZ temperatures will not affect cement. |
HEALTH HAZARD INFORMATION
| Handling | Cement may burn skin and very little heat may be felt. Wash the affected skin area thoroughly after exposure to dry powder and or wet cement (mixtures). Clothing which is covered with cement powder, dust and or wet cement should be laundered before the items of clothing are reword. |
| Effects of Exposure | Wet cement, when an ingredient in plastic concrete, slurries and or mortar, can dry unprotected skin areas and may cause caustic burns. If wet concrete comes into contact with the eyes it may cause irritation and, if swallowed (inhaled), may cause irritation to the upper respiratory system. |
| Cement dust may inflame the interior lining tissue of the cornea and nose. Exposure to the dust in some cases of extreme sensitivity may cause those individuals to develop and allergic dermatitis. | |
| Responses | If the eyes are affected pour clear water into the eye(s) for at least 20 minutes and alert a medical team or doctor. For exposed skin, wash the affected area with clean water and soap and remove any contaminated clothing. The medical team should be notified in the case of a large area of exposure. For inhalation of dust move the affected person(s) into the fresh air and keep them warm until the medical team arrives. |
| Cleanup Procedures | If a spillage occurs with cement powder it should be immediately cleaned up using a dry removal method which will not disperse dust into the atmosphere. Disposal of the cement must comply with local authority requirements. If cement is contaminated it may not be put back in original container(s). Cement powder must not be allowed to flow into storm water and or sewer drains. |
PROTECTION RECOMMENDATION
| Skin | If possible use barrier creams when working with cement and always shower after work when the work with cement has finished. Fresh protective clothing (except boots, glasses and gloves which may be reused where practicable) should be worn every day. |
| Eyes | Tight fitting goggles should be worn in dusty areas. |
| Breathing | An approved respirator (may be disposable) should be worn in dusty areas. |
| Ventilation | Exhaust fans close to the source of the dust are an effective method of reducing and controlling dust levels. However all discharge levels, etc. must comply with local authority requirements |
