Safe Lab Procedures and Tool Use
The workplace should have safety guidelines to follow to:
Protect people from injury
Protect equipment from damage
Protect the environment from contamination
Recognize Safe Working Conditions
Some things to look for:
Clean, organized, and properly lit workspace
Proper procedures for handling equipment
Proper disposal or recycling ponents containing hazardous materials
General Safety Guidelines
panies require reporting any injuries, including description of safety procedures not followed.
Damage to equipment may result in claims for damages from the customer.
CAUTION: Power supplies and monitors contain very high voltage. Do not wear the antistatic wrist strap when repairing power supplies or monitors.
CAUTION: Some printer parts may e very hot when in use and other parts may contain very high voltages.
Fire Safety Guidelines
Know the location of fire extinguishers, how to use them, and which to use for electrical fires and bustible fires
Have an escape route in case a fire gets out of control
Know how to contact emergency services quickly
Keep the workspace clean
Keep most solvents in a separate area
Have a fire plan before you begin work:
Electrostatic Discharge (ESD)
Static electricity is the buildup of an electric charge resting on a surface. This buildup may zap ponent and cause damage.
At least 3,000 volts of static electricity must build up before a person can feel ESD, but less than 30 volts of static electricity can damage ponent.
Preventing ESD Damage
Use antistatic bags to ponents
Use grounded mats on workbenches
