Capping of
reinforcing iron to prevent impalement is
required by 1926.701(b) which states that
all protruding reinforcing steel, onto and
into which employees could fall, shall be
guarded to eliminate the hazard of
impalement. Federal OSHA has interpreted
this standard to emphasize the effectiveness
of the protection.
Impalement
protection is provided by lumber supported
by systems such as by Steel high density
polymer reinforced caps.

“When employees are working at any height
above exposed rebar, fall protection/prevention
is the first line of defense against
impalement. Fall protection/prevention is
also applicable when the rebar is below
grade, e.g., footings or other excavations,
where a fall into a trench would present an
impalement hazard. When work is at grade,
impalement exposure is dependent upon
numerous situations and conditions;
proximity of rebar to worker, height of
rebar, e.g., working around rebar that is
3-6 feet high would not likely pose an
impalement hazard. Rebar caps/covers are
appropriate to prevent cuts, abrasions or
other minor injuries when working at grade
and there is no impalement hazard.
California
regulations require that manufactured caps
be at least 4 inches on a side or have a
diameter of 4.5 inches if rounded. Any
damaged cap of support system, including any
that have arrested a fall, must be replaced
immediately. Smaller “mushroom” caps do not
provide impalement protection but may be
used on horizontal rebar to prevent
abrasions, cuts and minor injuries and to
increase visibility. Maintaining supplies
of caps and/or supports throughout the site
encourages their immediate use. Mushroom
caps used on horizontal rebar should be of a
different color from caps used to prevent
impalement to facilitate usage control. Rebar
may also be bent over so that it no longer
presents an impalement hazard.
Regular use
of rebar caps is enhanced by worker training
and by maintaining supplies of capping
systems or caps in all areas of the worksite
where rebar is in place.

from falling onto protruding rebar. Caps may

Properly
designed rebar caps, as described in the
CalOSHA standard, spread the force generated
by a falling body through a large enough
area that impalement should not occur.
Other serious injuries may occur.

Rebar caps
can reduce the worst injuries from falls onto rebar. Primary methods to
to prevent falls and to arrest falls that occur must be used as required.
Safety on site
Protective cover
for rebar
Rebar can
cause nasty injuries and in the worst cases even
life threatening.
In practice, rebar often protected with plastic
cups, Styrofoam pieces, or the 'mushrooms'. This
might initially appear intact or scratches, but
in case of serious emergencies such offer no
protection. In
the United States is the protection of rebar
compulsory. . If someone seriously
injured in a fall on the site for the minutes
used in the legislation generic form of Article
312 of the act or Arbo-Risk Assessment and
Evaluation Requirement. So far so good
protection often depends on individual
initiative. Thus, BAM Building on two projects
recently screened the spot ends with the guards
for a British client who requires the protection
claimed.
The Suprotek protective plastic caps are
entitled to a rotating movement and the rebar
can be confirmed. They are available in two
variants. The
110 has a square platform and is suitable for
cutting ends of 8 to 18 mm. The 200 has a
plateau around and fit rebar from 20 to 45 mm. A
third implementation, D10, is designed for
horizontal thrust security rebar with diameters
of 8 to 18 mm. The caps are on the inside with
four terminal plates that hold the reinforcement
bar. While the
inside is not damaged, the cap can be used
repeatedly.
In drop tests, conducted by TNO Aboma + Keboma
and that the guards a significant contribution
to safety on the site. It had a height of four
meters weighing 105 kg on the caps fall. During
this drop the caps remained intact. The
valenergie released by the plastic cap included,
partly because a steel plate is included. The
caps are on the bright color in which they are
implemented. Thus, the rebar clearly
identifiable both on the ground and from the
tap. This alone is an important aspect that
accidents and mishaps occur.
Such accidents
are regular at work, often with unpleasant
consequences: the employee suffers an injury,
the employer costs due to absenteeism. The
Suprotek guards are designed to accidents at the
construction site and thus reduce the morbidity
and bring absenteeism costs down.
