What is the standard first-aid procedure when a crew member or victim is overcome by toxic gas inhalation (such as Chlorine or Hydrogen Sulfide) during a hazmat road incident?

1. Move the victim immediately to fresh air upwind, loosen constrictive clothing around neck and waist, keep them warm and at physical rest, administer artificial respiration (CPR) if breathing has stopped, and summon emergency medical services (120)
2. Give the victim hot alcoholic beverages and force them to run 5 kilometers to sweat out the gas
3. Leave the victim lying face down in the low-lying toxic ditch
4. Instruct the victim to hold their breath for 30 minutes
