What precaution should be taken regarding smoking at a work site?
Smoking should be prohibited at the work site, especially if there are flammables or explosive materials on site.
Describe one way to prevent hazards in the home.
Drugs and household cleaning agents, e.g., bleach, should be kept in closed cabinets or safely away from the reach of children.
What safety equipment should be provided at vantage points in case of fire outbreaks at a work site?
Fire extinguishers and fire blankets should be provided at vantage points to ensure easy access during fire outbreaks.
What should be done immediately to prevent slipping on a kitchen floor?
Spills on the kitchen floor should be cleaned immediately to prevent slipping.
How should the kitchen space be organized to prevent hazards?
