Looking ahead
An additional option that the
ASTM F18 committee is cur-
rently working on is to allow
OSHA-required (1910.137) pro-
tector gloves to be something
other than leather. The 90-year-
old technology of using rubber
insulating gloves for shock and
leather gloves for protection
of the rubber could be a thing
of the past through innovation
spurred on by the cut standards,
puncture standards and now the
arc flash standards for gloves.
Protecting workers from shock
and arc flash hazards while
using lighter and thinner gloves
that offer better grip, may not be
as far off as once believed. Nu-
merous countries subscribe to
the International Electrotechni-
cal Commission (IEC) standards.
The chairman of the ASTM F18
sub-committee responsible for
ASTM F2675 [5] is also part of
the IE CTC 78 Live Working
sub-committee; this is the IEC
committee that is working on
the arc rating standard for hand
protection. The latest feedback
is that the last meeting held in
Sao Paulo, Brazil, towards the
end of January 2014, resulted
in a draft scope, which will be
forwarded to the committee
members who will start formal-
ising a standard.
