HEALTH AND SAFETY PRODUCTS
GUIDELINES
SAFETY DO’S & DON’TS
The do’s & don’ts listed below are by no means fully exhaustive, you should also refer to the current issue of the Precast
Flooring Federation Code of Practice available on Tel: 0116 253 6161.
Health and Safety is a major concern for Bison, and we have developed a range of methods and systems which help to
ensure that anyone using Bison products can do so with minimal risk to themselves or others.
•
Do not alter the product without written permission from Bison Design Office, altering the product may compromise
its structural integrity and lead to failure. This includes notching, hole forming, shortening, narrowing the unit etc.
•
Do not alter the product in-situ, any permissible alterations must be completed on a flat stable platform. i.e. on the
ground or floor area.
•
Do not allow anyone to walk or work beneath the product whilst it is being hoisted or suspended.
•
Do not work in areas without the appropriate perimeter edge protection, handrails, guardrails, platforms or stages.
•
Do not access working areas without properly constructed, maintained, secured and illuminated, stairways, ramps,
ladders or the like.
•
Where lifting hooks are specified within a contract, do hoist the units by crane using ALL the lifting points in the top
surface provided for that purpose. Prior to lifting safety chains must be loosely slung around the underside of the
unit. The safety chains may only be released immediately before the slab is placed in its final position.
•
For insurance purposes, Bison do not supply or hire lifters or chain sets. Please refer to our information sheets for
details of supplier hire or purchase.
•
Do not run plant or store equipment on the precast floor before it is grouted and cured. Once cured do not exceed
the loads specified by the engineer.
•
Do use a passive fall protection system wherever reasonably practicable considering all heights where the potential
fall distance could result in an injury.
•
Do ensure the perimeter scaffolding is positioned no more than 900mm below the top surface of the flooring, or landing level.
•
Do ensure all voids created whilst placing units are adequately protected during and after erection.
•
Do ensure all brickwork, blockwork or concrete is adequately cured, stable and fit to receive precast concrete units,
and that steelwork is stable.
•
Do ensure the stability of support beams, lintels etc. is considered, particularly the rotation of support member due
to unequal loading.

Do ensure you include allowance for site handling by referring to the unit weight table.
