LAB HAZARDS PERSONAL PROTECTIVE EQUIPMENT

Machinery  Eye Protection: NA

 Clothing: No loose clothing, no unsecured long hair, close toed shoes

 Additional PPE: gloves

LAB RULES 1. Machinery

 Close-toed shoes (leather, if welding) are required. Always secure anything that might get caught in moving machinery, such as long hair, jewelry, ID badges, loose clothing, and neckties.

 Never use a machine if you are not trained on it.

 Never remove safety guards. Never bring your hands close to sharp objects.

 Never work alone – there must always be at least two adults in the lab, and machinery cannot be used outside of supervised lab hours.

 Never use machinery when impaired or tired. Never start work if you cannot do the job safely.

 Work area around machine should be neat and orderly - always clean up after yourself. All tools must be returned, the machine cleaned and the floor swept. Do not remove metal chips, turnings, or shavings with your hands. Leave 10-15 minutes for cleanup.

 Always report broken or damaged tools, or abnormal equipment function to the lab director so that it can get repaired.

 No eating in the lab. SAFETY

 Work with materials only after you have learned about their flammability, reactivity, corrosiveness and toxicity. Colored diamond shaped labels on the reagent bottles can provide some of this information. For additional information you can request Material Safety Data Sheets which are available in the laboratory and online.

 Although pregnancy is a personal issue, for your health and the health of your child, please inform your instructor if you are pregnant. Consult with your physician! We want to make sure you and your physician are aware of the chemicals that will be used in the lab so that you are able to make an informed decision about continuing with a laboratory course.

 Know the types of protective equipment available and proper type for each job.

 Know the location of, and how to use, safety equipment such as fire blankets, eye washes, and safety showers.

 Know the safety rules and procedures that apply to the work to be done.

 Be alert to unsafe conditions and actions and call attention to these so the corrections can be made as soon as possible.

 Be certain that all chemicals are correctly and clearly labeled. Post warning signs when unusual hazards exist.

 Use equipment only for its designated purpose.

 Heat solutions in test tubes so that there is no hazard to self or neighbors.

 Construct and clamp reaction apparatus thoughtfully in order to permit manipulation without the need to move the apparatus until the entire reaction is completed.

 Use a plastic safety bucket when transporting liquid chemicals, reactive solids, and large amounts of glass equipment within or between buildings

 No persons other than other research group members are allowed in the laboratory without permission of your research advisor. All visitors are required to wear protective eye wear.

 Wash your hands thoroughly before leaving the laboratory.

 Think, act, and encourage safety until it becomes habit.
