There may also be other unmapped services present, and services owned by diff erent parties. The steepest slope at which an excavated face is stable against slips and slides, having regard to the qualities of the material in the face, the height of the face, the load above the face and the moisture conditions for the time being existing. Alternatively, shoring designed to specific soil load profiles (eg trench shields). Otherwise, a competent person should design the shoring for the specific workplace conditions. 0000035299 00000 n Mapei New Zealand Ltd., 30 Fisher Crescent, Mt Wellington, Auckland 1060, New Zealand Phone +64 9 921 1994 Fax +64 9 921 1993 Email [email protected] This website uses cookies to improve your browsing experience.

For more information on controlling the risks of manual handling, refer to WorkSafe’s Code of practice for manual handling. PCBUs must always eliminate a risk if this is reasonably practicable. In this case, strengthen the ground support system at these locations and provide barriers to prevent the material falling into the excavation. Underground cables. Telephone cables were employed for aerial, underwater and underground … Frequently inspect pressure hoses and rams to detect abrasion, fatigue, or damage such as bent or notched rams. Place toms safely from outside the excavation, E. For added side support, steel struts may replace timber toms, G. Securely nail cleats to soldiers before placing soldiers, H.

Provide induction-training programs emphasising the dangers of working in close proximity to mobile plant, and provide adequate supervision. More than one PCBU can have a duty to the same matter. If the conditions during construction are not as expected, or if conditions change during the course of the work (eg different soils, heavy rain/flooding) take immediate action to protect workers, other people and property. taking reasonable care of their own health and safety, taking reasonable care what they do (or fail to do) does not cause harm to any other person, operating with any reasonable health and safety policy or procedure of the PCBU, complying, so far as reasonably able, with any reasonable instruction given by the PCBU, so the PCBU can comply with the law, using or wearing PPE in accordance with any information, training or reasonable instruction given by the PCBU, not intentionally misusing or damaging the PPE. 0 Complete Underground Services offers complete drilling services in and around Auckland. Our plant has both manual and fully automated spray equipment to handle large production runs. identify hazards that could reasonably foreseeably create a risk to health and safety, eliminate the risk so far as is reasonably practicable, if it is not reasonably practicable to eliminate the risk – minimise the risk so far as is reasonably practicable, maintain the implemented controls so they remain effective.
