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.
