Hey, you got brake and break right. Chock and chalk are kinda minor in comparison... Do NOT skip the hearing protection. Take it from someone with a serious hearing loss: that's not something you want to live with. Instead, if your company allows it, consider something like this: https://www.cabelas.com/product/IMPACT-SPORT-ELECTRONIC-EARMUFF/2225038.uts That will protect your hearing while still letting you hear around you. Even have a conversation. There are lots of models; wouldn't surprise me if there is one made specifically for industry as well as shooting. EDIT: oh, and if you balk at the price...my hearing aids are $3,500... each. Insurance that pays for them is quite rare.
