If you are working where there is an arc or fire hazard; on powerline clearance work or around wildland fires, then you need to make sure that your chainsaw protection will protect you. It has to be fully fire resistant. Look for the Arcmax logo. It’s different. As far as we know, it’s also a world first. The chainsaw protective fabric has been specially developed to be fire resistant. It will not ignite. It will not melt. It will not drip.
