Use these safety moments as you see fit.

• Feel free to adapt a safety moment to meet the
  specific needs and time constraints of an
  audience or occasion this may mean using only a
  portion of the prepared slides for a topic or
  including additional
• resources for an in-depth discussion.

Importance of a Clean Lab Coat

• Wearing a seriously soiled lab coat is like
  wearing hazardous waste!
• Chemistry department now offers a FREE lab coat
  laundering service
• Monthly service

7
How it works

• Every 4th Wednesday
• Drop off dirty lab coats to Smith S18
• Make sure your name is written on the pocket (not
  collar)
• There will be two hampers
• Coats that DO have the vendors barcode in the
  collar
• Coats that DO NOT have the vendors barcode in
  the collar.
• Look for a monthly email reminder
• Thursday afternoon, 4 weeks later
• Pick up your clean lab coat from Smith S18

Proper Lab Attire
9
Proper Lab Attire

• Clothing must cover the arms and legs
• Tights/leggings are not appropriate
• Short sleeves are okay if lab coat is worn
• Loose or draping clothing (i.e. scarves) is
  unsafe
• Long hair should be tied back

10
Proper Lab Attire

• Shoes must cover the entire foot
• Leather or synthetic leather
• Shoes with traction are preferable
• Steel-toed shoes are required when transporting
  heavy equipment
• Socks should cover ankles.

Gloves

• Best practices for wearing disposable gloves

12
Gloves

• Select gloves made of material known to be
  resistant to permeation by the substances in use.

• 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

Gloves

• Replace gloves when
• Contaminated
• Permeated by solvent
• Torn
• You have been wearing them awhile
• 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

14
Gloves

• Remove gloves before leaving lab area.
• Remove in a way that avoids skin contact
  contaminated glove exterior
• Dispose of gloves in non-hazardous (normal) trash
• If radioactive chemicals were used, place
  in radioactive waste.

protective-Equipment/Hand-Protection

• Wash hands
• Do not attempt to re-use disposable gloves.
• Increased risk for contamination

15
Gloves

• To prevent the unintentional spread of hazardous
  substances, when wearing gloves dont touch
• Anything used outside the lab
• Doorknobs, personal telephones, pens, etc.
• Your face or clothes

If you are transporting a chemical in the
hallway, only wear a glove on one hand.

• Have a policy (gloves or no gloves) for lab
  computer use.
• Post your policy on the computer to remind
  visiting researchers.

Glove Usage

• 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.

Respiratory Hazards

• Is a respirator needed?
• How can you get one?

35
Respiratory hazards

• Aerosolization during common lab procedures
  e.g., weighing solids for making solutions
  Tris, SDS, Ascorbic acid, MES hydrate.
• Harmful/irritating to the eyes and lungs.
• PPE
• Gloves, goggles, lab coat. In general read MSDS
  before using any chemicals, and possibly
  respiratory mask.
• Upon exposure
• Eyes Rinse at the eye shower
• Inhalation Move to fresh air, seek medical aid
  if experiencing discomfort

36
Respiratory Protection Program

• Check the MSDS to determine if a respirator is
  needed for the chemicals you are working with.
• If use of a respirator is required, DEHS will
  provide you with information to enroll in the
  Universitys Respiratory Protection Program
  through the Office of Occupational Health
• Information on the Respiratory Protection Program
  can be found at http//www.ohs.umn.edu/rpp/home.h
  tml
• Minimum requirements for the program include
  filling out a health survey and a fit test for
  the type of respirator you will be using
• Additional information is available through the
  website
