(a)
At Lourdes Empinado National High School, the Grade 7 students are scheduled to perform an experiment involving chemical substances. Before entering the laboratory, their teacher, Mr. Cruz, reminds them about the importance of wearing proper Personal Protective Equipment (PPE).
Each student is required to wear a lab gown to protect their skin and clothing, safety goggles to shield their eyes from splashes, and gloves to avoid direct contact with hazardous chemicals. The teacher also reminds them to wear closed shoes to protect their feet and a face mask to prevent inhaling any harmful fumes. Maria, one of the students, forgets her gloves and is told to wait outside the lab until she borrows a pair.
Later that day, another group of students goes to the construction workshop to practice woodworking. Before starting, the teacher, Mr. Ramos, ensures that all students wear helmets, safety gloves, and protective eyewear. One student, John, tries to enter the workshop wearing slippers and is immediately stopped and told to change into industrial boots.
In both situations, proper PPE ensures the safety and protection of students from possible injuries and exposure to risks. Following these safety rules is part of Occupational Health and Safety standards that everyone must follow in any potentially hazardous environment.

Arriving early
One rainy afternoon, the computer lab at Lourdes Empinado National High School experienced a sudden power outage. When the electricity came back, one of the computers failed to turn on. Mr. Cruz, the computer technician, was called to fix it.
Before starting, Mr. Cruz made sure to wear his anti-static wrist strap to prevent damage from electrostatic discharge. He also turned off the power source and unplugged the computer before opening the system unit. Upon checking, he found that the power supply unit (PSU) was damaged due to the sudden voltage surge. He carefully replaced the PSU with a new one.
While working, he noticed that the RAM was not properly seated in its slot. Using proper tools like a screwdriver and flashlight, he gently secured the RAM into place. After double-checking all connections, he closed the case, plugged the power cord back in, and turned the computer on. This time, it booted successfully.
Mr. Cruz reminded the students watching him that safety procedures and proper handling of components are very important when fixing a computer. He also advised them to always use a voltage regulator or UPS (Uninterruptible Power Supply) to protect their computers during storms or power interruptions.
