ACMT Tools, Safety & ESD Procedures 2

Question 1

What is the correct procedure for handling a swollen lithium-polymer battery found during a Mac repair?

Accepted Answer

Do not puncture or compress; place in a fire-proof container, handle with care, and follow local hazardous waste disposal procedures

Answer

Swollen LiPo batteries are a fire and explosion hazard; they must never be punctured, compressed, or charged, and must be disposed of according to local hazardous material regulations.

Question 2

Why must a technician disconnect the battery before working on a MacBook's logic board?

Accepted Answer

To eliminate the risk of short circuits and component damage from residual current while handling circuit board components

Answer

Even with the MacBook powered off, the battery provides voltage that can flow through the board; disconnecting it eliminates the risk of short circuits that can destroy components.

Question 3

Which chemical solution is approved for cleaning logic board contamination (such as liquid damage residue) on Macs?

Accepted Answer

99% isopropyl alcohol (IPA) applied with an ESD-safe brush

Answer

99% isopropyl alcohol evaporates quickly without leaving residue and is safe for PCBs, making it the approved cleaner for liquid damage corrosion on Mac logic boards.

Question 4

What personal protective equipment (PPE) should a technician wear when cleaning a liquid-damaged Mac?

Accepted Answer

Nitrile gloves and eye protection to protect from chemical residue and isopropyl alcohol

Answer

Nitrile gloves protect skin from corrosive residue and IPA, while eye protection prevents chemical splashes, making both necessary for liquid damage cleaning procedures.

Question 5

A technician is using a spudger during a MacBook repair. What is the primary purpose of this tool?

Accepted Answer

Prying apart components and routing cables without causing ESD or scratching delicate surfaces

Answer

A spudger is a non-conductive, non-marring plastic or nylon tool used to pry, route, and lift cables and connectors without scratching surfaces or creating ESD damage.
