A health hazard is different from a safety hazard. When your wellbeing is concerned, it can be a hazard to be exposed to a substance, thing, animal other than man, plant, gas, liquid, or solid that can harm your health. Exposure to black mold, gas leaks, rats and mice, poison ivy, gasoline, and bacteria and viruses can cause harm to your health. Safety hazards can be present anywhere, like the workplace or home.
Falls can occur any time by not taking precautions of keeping stairways cleared for passage, tripping over something on a sidewalk, or a pothole in the road. Safety hazards culminate due to carelessness like leaving the stove unattended, leaving plastic bags or medications out so that a small child could get them, and leaving matches and lighters on tables. Whether the hazard is health or safety-related, the best course of action is to be aware of your surroundings and be cautious.
