Using a safety shower correctly is crucial during a chemical or hazardous substance exposure to minimize injury. Here's a step-by-step guide:
When an accidental exposure to hazardous materials occurs, immediate action is required. A safety shower provides a quick and effective way to drench the body and dilute or remove contaminants from the skin and clothing. Time is of the essence, so knowing the procedure beforehand is vital.
Steps for Using a Safety Shower
Follow these steps immediately upon exposure to a hazardous substance:
- Locate the Nearest Safety Shower: Know the location of safety showers in your work area before an emergency happens. They are often marked with highly visible signs.
- Activate the Shower: Most safety showers are operated by means of a pull lever. Grab the handle firmly and pull it down quickly. This action opens the valve, initiating the flow of water.
- Get Under the Water: Immediately step under the stream of water. Ensure your entire body, especially the affected areas, is completely saturated.
- Remove Contaminated Clothing: While under the shower, quickly remove any clothing, jewelry, or personal protective equipment (PPE) that may be contaminated. This is a critical step as clothing can trap chemicals against the skin, prolonging exposure. The water will help to wash away contaminants as you remove items.
- Rinse Thoroughly: You should stay under the stream of water for at least 15 minutes to ensure thorough decontamination. According to ANSI regulations, once the lever has been pulled, the shower will discharge water at a specific rate and volume for at least 15 minutes. Use your hands to wash affected areas gently.
- Seek Medical Attention: After completing the 15-minute rinse, seek immediate medical attention. Even if the exposure seems minor, a medical professional should assess the extent of the injury and provide appropriate treatment.
Key Considerations
- Speed: Reaction time is critical. Get to the shower and activate it within seconds of exposure.
- Duration: The full 15-minute drench is necessary for effective decontamination. Do not leave the shower early unless instructed by emergency personnel.
- Clothing Removal: This step is non-negotiable for effective rinsing.
- Medical Follow-up: Always seek medical evaluation after using a safety shower for a chemical exposure.
Understanding and practicing these steps can make a significant difference in the outcome of a hazardous material exposure incident.
