- 2. INTEND LEARNING OUTCOMES Atthe end of this Chapter, the students expected to: • Know how to work safely inside the laboratories; • Explain the Guidelines for Basic Safety Practices; • Explain the functions of Hardware Tools; • Apply the tools and software to be used in personal computer; • Know the Software Tools; • Familiarize the computer components and its purpose; and • Train on how to properly practice the different computer tools. CHAPTER 9
- 3. GUIDELINES FOR BASICSAFETY PRACTICES IN THE I.T WORKPLACE INJURY PREVENTION FOLLOW & BE ALERT TRAIN & USE TOOLS WISELY BE PROFESSIONAL & HEALTHY
- 4. CAN YOU RECOGNIZESAFE WORKING CONDITION? CLEAN AND ORGANIZE PROFESSIONAL TECHNICIANS
- 5. GENERAL SAFETY GUIDELINES REPORTINCLUDING THE DESCRIPTIONS PREVENT INJURIES CAUTION: • Power supplies and monitors contain very high voltage. • Do not wear the antistatic wrist strap when repairing power supplies or monitors. • Some printer parts may become very hot when in use and other parts may contain very high voltages. 1. Dangers of working on computers – List possible dangers 2. Precautions and warnings – List ways to protect technicians 3. Share a story about damage to equipment or an injury due to lack safety procedures CUTS BURNS ELECTRICAL SHOCK DAMAGE TO EYES POSSIBLE DANGERS TO A TECHNICIANS
- 6. FIRE SAFETY GUIDELINES •KNOW THE LOCATION OF FIRE EXTINGUISHER AND LEARN HOW TO USE IT • HAVE AN ESCAPE ROUTE • KNOW HOW TO CONTACT EMERGENCY SERVICES QUICKLY • KEEP THE WORKSCPACE CLEAN • KEEP SOLVENTS IN SEPARATE AREA HAVE A FIRE PLAN BEFORE YOU BEGIN WORK: • P – PULL THE PIN. • A – AIM AT THE BASE OF THE FIRE, NOT AT THE FLAMES. • S – SQUEEZ THE LEVER. • S – SWEEP THE NOZZLE FROM SIDE TO SIDE HOW TO USE FIRE EXTINGUISHER?
- 7. ELECTROSTATIC DISCHARGE (ESD)AND HOW TO PREVENT IT ELECTROSTATIC DISCHARGE (ESD) Static electricity is the build up of an electric charge resting on a surface. This buildup may zap a component and cause damage. This is known as electrostatic discharge (ESD). ESD can be destructive to the electronics in computer components. PREVENTING ESD DAMAGE • Keep all components in antistatic bag until you need them. • Use ground mats on workbenches. • Use grounded floor mats in working area. • Use antistatic wrist strap when working on computers. CLIMATE THAT AFFECTS THE COMPUTER EQUIPMENT: • If the environment temperature is too high, equipment can overheat. • If the humidity level is too low, the chance of ESD increases. • If the humidity level is too high, equipment can suffer from moisture damage.
- 8. POWER FLUCTUATION Computer circuitsneed voltage and current to operate electronic components. Unsteady voltages are called power fluctuation. TYPES OF AC POWER FLUCTUATIONS • BLACKOUT • BROWNOUT • NOISE • SPIKE • POWER SURGE SHIELD FOR POWER FLUCTUATION • SURGE SUPPRESSOR • UNINTERRUPTIBLE POWER SUPPLY (UPS) • STANDBY POWER SUPPLY (SPS)
- 9. MSDS AND PROPERDISPOSAL MSDS is a fact sheet summarizing information about materials identification, including hazardous ingredients that can affect health , fire hazards, and first aid requirements. MATERIAL SAFETY DATA SHEET (MSDS) PROPER DISPOSAL CONTACT THE LOCAL SANITATION COMPANY
