First Aid, Medical Needs, Bloodborne Pathogens, and Universal Precautions

Medical Readiness

Construction medical planning must fit the site. Likely events include cuts, burns, eye injuries, falls, struck-by injuries, crush injuries, electrical shock, heat illness, cold stress, respiratory exposure, and cardiac emergencies. The plan should consider crew size, shift schedule, site access, distance to EMS, language needs, remote work, work at height, confined spaces, and rescue difficulty. A first aid kit in a trailer is not enough if the injured worker is six floors up and EMS cannot find the gate.

Where EMS is not reasonably accessible in time, trained first aid providers may be required. Even when EMS is nearby, trained workers can activate response, control bleeding, start CPR or AED use when trained, flush eyes, cool heat illness, and guide responders. The EAP should tell workers how to report injuries and who meets EMS.

Scene Safety and First Aid Limits

Scene safety comes first. A responder should not enter an energized area, traffic lane, unstable excavation, confined space, fire area, chemical release, or collapse zone without proper training and controls. Creating another victim worsens the emergency. The correct first actions are to assess hazards, call for help, control the scene if safe, and provide care within training.

EMS should be activated for serious bleeding, loss of consciousness, chest pain, breathing difficulty, suspected stroke, severe burns, electrical shock, suspected spinal injury, major fracture, heat stroke signs, chemical exposure, amputation, crushing injury, or any condition beyond first aid.

First aid supplies should be inspected, stocked, visible, and protected from contamination. Higher-risk sites may need AEDs, eyewash, emergency showers, stretchers, rescue baskets, trauma kits, or heat illness cooling supplies.

Universal Precautions

Universal precautions mean treating blood and certain body fluids as potentially infectious every time. The responder does not judge risk based on appearance or job title. Controls include gloves, eye and face protection for splash risk, CPR barriers, hand hygiene, disinfectant, biohazard bags, and sharps containers when needed.

Bloodborne pathogens include hepatitis B, hepatitis C, and HIV. Construction workers may encounter blood during first aid, cleanup, discarded needles, or contaminated debris. Workers with reasonably anticipated occupational exposure need training, PPE, cleanup procedures, and an exposure reporting process.

If blood or potentially infectious material contacts broken skin, eyes, mouth, mucous membranes, or enters through a needlestick or cut, the worker should wash or flush immediately, report the exposure, and receive medical evaluation according to the exposure control plan. Cleanup should be performed by trained personnel. Do not pick up broken glass or sharps by hand. Dispose of contaminated material properly and wash hands after glove removal.

• Do not delay EMS activation for paperwork.
• Keep medical access routes open.
• Document care, witnesses, and follow-up.
• Respect medical restrictions before return to work.
