Module 10.1 - Learning objectives
- Have a basic knowledge of common emergency devices within a lab setting
- Be familiar with how these devices function
Module 10.2 - Emergency devices
While everything is planned to proceed under normal and safe circumstances, there are situations that must be prepared for. There are different types of emergency devices within lab spaces, including:
Fume hood purge buttons
Upon activation, a temporary increase in face velocity within the fume hood is activated and is intended to assist in clearing contaminants. Note that not all fume hoods are equipped with a purge button; therefore, it is important to familiarize yourself with the fume hood that you will be working in.
Emergency showers
Provide a steady flow of water (75.7 litres per minute) for at least 15 minutes. New facilities (for example, in STEM and ARC) are supplied with tepid water, while historical units elsewhere on campus are supplied with cold water. If exposed to chemical products, it is generally recommended to douse the affected area(s) with copious amounts of water to flush the contaminated surfaces for at least 15 minutes. It is critical that contaminated clothing be removed while under the shower. There is no time for modesty when dealing with strong corrosives. In certain buildings with cold water units, there are warm-up showers in the washrooms, which are to be used for the sole purpose of post-exposure emergency response. Shower activations are immediately and automatically reported to Protection Services. Emergency showers are activated by pulling the handle located overhead.
Emergency eyewashes
Provide a steady flow of water (1.5 litres per minute) for at least 15 minutes. As with emergency showers, flushing with water is a critical early intervention. Because these units are more easily managed, lab users are required to regularly inspect their emergency eyewashes in accordance with the type of facility (tepid water stations require weekly inspections, whereas cold water stations require monthly inspections). An eyewash checklist (PDF, 483KB) is available to guide users during this inspection. There are several types of eyewashes on campus, which have slightly differing means of activation. Ensure you familiarize yourself with how the units nearest you operate.
