Maintain Healthy and Safe Environment
What this domain covers
This domain tests infection control, food safety, waste management, hazard control, and safe physical spaces. Questions often present a risky room or routine and ask what to fix first.
Core rules
- Hand hygiene and PPE: wash hands before and after care; use gloves for body fluids; disinfect shared surfaces.
- Waste segregation: separate biodegradable, recyclable, residual, and special waste under RA 9003.
- Food safety: clean, separate raw and cooked food, cook thoroughly, and chill promptly; keep food out of the 5-60 °C danger zone.
- Chemical safety: store cleaners and medicines locked, labeled, and out of reach; never place them in food containers.
- Child safety: keep small objects from toddlers, choose age-labeled toys, cover sockets, and supervise water.
- Air, light, and pests: ventilate rooms, maintain lighting, and control pests without exposing clients to poison.
- Emergency readiness: post emergency numbers and keep a fire extinguisher and clear escape route.
Worked example
A toddler room has small beads on the floor and bleach in a soft drink bottle. The caregiver removes the beads, transfers the bleach to a locked original container, chooses larger toys, and informs the family. Reasoning: the beads are a choking hazard and the bottle invites poisoning; original containers prevent dangerous confusion.
Traps that lose marks
- Mixing bleach with ammonia.
- Storing chemicals in food or drink containers.
- Ignoring small toy parts around infants.
- Overloading electrical sockets.
