Quick Answer
When handling unknown chemicals outdoors, always wear protective gear, maintain a safe distance, and have a plan for decontamination and evacuation in case of exposure. Monitor the chemical's properties, such as its volatility, reactivity, and potential for skin absorption. This will help you take the necessary precautions.
Assessing the Chemical Hazard
When confronted with an unknown chemical, assess its hazard potential by checking its labeling, color, and any visible signs of reactivity. Be cautious of chemicals with bright colors, unusual smells, or those that produce gas or foam. Familiarize yourself with the chemical’s properties to understand its potential risks. Some common hazards to look out for include: skin and eye irritation, respiratory problems, and fires or explosions.
Improvised Protective Gear
If you don’t have access to proper personal protective equipment (PPE), improvise by using items like gloves made from materials like rubber, canvas, or plastic bags, and goggles fashioned from plastic bottles or glasses. In the absence of a face mask, cover your nose and mouth with a cloth or a bandana to filter out airborne particles. Remember that these improvised measures are temporary solutions and should not be relied upon for extended exposure.
Evacuation and Decontamination Protocols
In case of exposure, quickly move to a safe area, ideally upwind from the chemical source. Remove contaminated clothing and wash your skin and hair with soap and water. For chemical splashes, flush the affected area with water for at least 15 minutes. If the chemical has entered through the eyes, flush them with water for 10-15 minutes and seek medical attention if irritation persists.
