I would like to add to the list:
Personal Safety
1) Keep a two day supply of your prescription medications in your truck AND a note list of any medical conditions that might leave you unable to respond to the EMS, ie: Diabetes, Heart Conditions, COPD, Hypoglycemia...you get the idea
2) A liquid and or jell-cap ANTIHISTAMENE, such as Benadryl, to counteract allergic reactions to foods, bites and stings from bugs, spiders and bees. It can slow down or stop anaphylactic shocks.
ASK YOUR DOCTOR
3) Know the signs of heat stroke and hypothermia, have a plan for each one.
4) A personal data sheet: If you are unconscious and EMS or your fellow employees need to know; Your Name and address & phone numbers, medical conditions if any, medications you are taking, your doctors names & phone numbers, who to contact & phone number for permission to treat you if, needed ANYTHING that might effect your treatment if injured or unconscious.I have been in the heavy/highway industry for 45 years and have seen the results of the preparing AND not preparing for the above issues and those I posted earlier.
