The following steps are included in a five-and-five approach
Give 5 back blows:
In this step, stand behind the person who is choking. Bend the person so that he/she is parallel to the ground. Place a hand on his/her chest. Give five separate back blows with your hands.
Give 5 abdominal thrusts:
Give five separate abdominal thrusts to the person who is choking.
Alternate between 5 blows and 5 thrusts:
Alternate between back blows and thrusts until the blocking starts to dislodge.
If your boss tells you to watch out then do it. Your boss is like your "guardian" at your job. Chemicals are dangerous. Its your job to listen and take your bosses advice at your job.
I hope this is what you needed and I hope this helped! :)
