has placed increasing emphasis
on ensuring that material supplied meets or exceeds the
normal safety requirements for concrete construction.
Do not use any Masons product before first reading and

involved in the application of that product. In concrete

formwork, unsymmetrical placement of concrete, uplift,

impact, use of motorized carts, formwork height, jerking of a
crane during the lifting of concrete elements, use of a crane
adequate for the job, bouncing of the concrete elements
after it has been lifted, are some the conditions that have a
high risk factor. Safety factors must be increased by the user
to reduce these risks. It is for this reason that we state the
minimum safe working loads of the products we represent.
Masons recommends that the provisions of the American
National Standards Institute's (ANSI A 10.9), OSHA
(Occupational Safety and Health Administration Act,
Part 1926) and the American Concrete Institute's Guide
to Formwork for Concrete (ACI 347) be strictly followed
when considering safety factors and safe working loads.
We especially advise that the minimum safety factors
listed below be adhered to. When there are unusual job
conditions, these minimum safety factors must be increased
by the user.
