Safety Moments Topic: Personal Protective Equipment A Safety Moment is a brief safety talk about a specific subject at the beginning of a meeting or shift. Also known as safety minutes or safety chats, these talks can be done in a variety of ways, but are typically a brief (2-5 minute) discussion on a safety related topic. They can cover a variety of safety topics and remind employees of the importance of being safe; at work, at home and in all aspects of our lives. Use one slide per Safety Moment (unless specified).

PPE and Chemical Packages PPE required to transport chemicals within and between labs Best practice suggests PPE should be worn when opening packages containing chemicals Packaging is form of engineering control PPE protects in case that control fails http://www.jst.umn.edu/safety-moments

Cryogen vs. Autoclave Gloves Autoclave gloves (aka Bel-Art gloves) are made of loosely-woven cotton Heat resistant up to 232 °C, but woven cotton provides little protection to cold gases or liquids Cryogenic gloves are made of nylon and PTFE and thus could melt at higher temperatures Temp range of -260 to -300 °C http://www.sigmaaldrich.com/catalog/product/aldrich/z4084 92?lang=en&region=US

Flame resistant sleeves $11.00 per pair vs. ~$100 for a full lab coat Fits over normal lab coat sleeve Protects part of arm most likely to come in contact with flammables while working in the hood http://workingperson.com/national-safety-apparel-16-9oz- fr-green-sateen-sleeve-sewn-in-elastic- s02grrg02.html#details

Glove Usage http://www.dehs.umn.edu/PDFs/gloves.pdf Wear gloves of a material known to be resistant to permeation by the substances in use. Look for an expiration date on individual packages of gloves. Before use, check gloves (even new ones) for physical damage such as tears or pinholes. Check reusable gloves for previous chemical damage. Dispose of gloves when they show any sign of leakage or deterioration. Select gloves of the correct size and fitting. Some gloves, especially lightweight disposables, may be flammable: keep hands well away from flames or other high temperature heat sources. Replace gloves periodically, depending on the frequency of use and their permeation and degradation characteristics relative to the substances handled. Remove gloves before handling objects such as doorknobs, telephones, pens, and computer keyboards. When removing gloves, do so in a way that avoids skin contact with a possibly contaminated glove exterior. Always wash hands after removing gloves. Dispose of contaminated gloves properly. Do not attempt to re-use disposable gloves. http://www.dehs.umn.edu/PDFs/gloves.pdf

Gloves the Basics (slide 1 of 2) Select gloves made of material known to be resistant to permeation by the substances in use Lab Safety Supply Company provides chemical compatibility guide for gloves at http://www.labsafety.com/refinfo/ezfacts/EZ166.pdf. Check gloves (even new ones) tears or pinholes Select gloves of the correct size and fit Too small  uncomfortable and may tear Too large  low dexterity Remove rings and jewelry that can tear gloves Replace gloves when Contaminated Permeated by solvent Torn You have been wearing them awhile

Gloves the Basics (slide 2 of 2) Some gloves, especially lightweight disposables, may be flammable Keep hands well away from flames or other high temperature heat sources Consider double gloving, if working with A highly hazardous compound Radioactive materials Situations were there is a high potential for spills or splashes Remove gloves before leaving lab area. Remove in a way that avoids skin contact contaminated glove exterior Dispose of gloves according to hazardous waste policy Wash hands Do not attempt to re-use disposable gloves. Increased risk for contamination
