Laboratory aprons

Safety goggles and a laboratory apron must be worn whenever you work in the lab. Gloves should be worn whenever you use chemicals that cause irritations or can be absorbed through the skin.

Wear laboratory aprons in the laboratory. Keep the apron strings tied so that they do not dangle. 

Use care when handling hydrochloric acid and hot objects. Wear goggles and laboratory aprons. Perform this ChemLab in a well-ventilated room. 

Store wearing apparel in appropriate places. Laboratory aprons must not be hung on the same rack with personal clothing. 

Use latex gloves, impervious laboratory apron or clothing, and full-face shields when handling these compounds. In the event of a spill, wipe up with absorbent paper and then clean with methylene chloride, methanol, and a detergent. The contaminated papers, clothing, and so on, should be placed into a hazardous waste drum. Contaminated glasses should be compacted in a hazardous waste trash compactor and placed in a waste disposal drum. Effluents from hoods, GC/MS, and vacuum pumps should be passed through HEPA particulate Alters and charcoal. 

For their safety, the human subjects should not be permitted to leave the laboratory test area for any reason, once testing begins, since their hands will be contaminated with E. coli. Additionally, subjects should be required to wear protective laboratory aprons and be instructed not to touch their garments, faces, or any other body parts with their contaminated hands during the testing period. 

Laboratory aprons are often underutilized for protection. They can prevent chemical exposure to the front of your body and should be considered for use over your lab coat. Rubber aprons have been used for many years and are thick enough to offer considerable protection against spills and splashes of many chemicals. Lab aprons made of the same kind of material as chemical-resistant lab coats are also available. 

Always wear closed shoes in the laboratory open-toed shoes or sandals offer inadequate protection against spilled chemicals or broken glass. Do not wear your best clothing in the laboratory because some chemicals can make holes in or permanent stains on your clothing. To protect yourself and your clothing, it is advisable to wear a full-length laboratory apron or coat. 

CAUTION All operations with trimellitic anhydride (or acid) must be carried out in a well-ventilated hood using proper personal protection such as gloves, laboratory apron-coat, and chemical goggles. Exposure to trimellitic anhydride may cause eye or skin irritation or lung irritation (pulmonary edema).
