ObjectivesObjectives

• To recognize agency who regulates the use of PPEPPE

• To apply employee safety and protection• To review the main aspects of the PPEPPE Program• To describe a Job Hazard AnalysisJob Hazard Analysis• To recognize lines of defense• To choose the proper PPEPPE in controlling

exposure to hazards in the laboratory

What is PPE?What is PPE?

• PPEPPE is designed to protect employees from serious workplace injuries or illnesses resulting from contact with chemicals, radiological, physical, electrical, mechanical or other workplace hazards.

• Occupational Safety Health Administration –OSHA- regulates the use of PPE

What is Job Hazard Analysis?What is Job Hazard Analysis?

• A Job Hazard AnalysisJob Hazard Analysis is a technique that focuses on job tasks as a way to identify hazards before they occur. It focuses on the relationship between the worker, the task, the tools, and the work environment. Ideally, after you identify uncontrollable hazards, you will take steps to eliminate or reduce them to an acceptable risk level

Engineering Controls-1Engineering Controls-1

• First line of defenseFirst line of defense– To eliminate or reduce exposure to hazards by

physically removing or reducing the hazard• Example: Fume hoods, ventilation systems,

equipment and machine guards– Engineering controls may require modifications or

substitutions of equipment or materials to accommodate current activities and reduce potential hazard

• Using a less hazardous chemical• Increased ventilation

6/27/2011 6

– Work must be discontinued if the engineering control is not functioning correctly.

• Example: Fume hood stops working• Building must be evacuated when there is a loss of

power

Engineering Controls-2Engineering Controls-2

6/27/2011 7

Administrative Controls-1Administrative Controls-1

• Second line of defenseSecond line of defense– To eliminate or reduce exposure by workplace

policies and procedures. (review Lab Safety Manual)– These controls are hazard avoidance rather than

control. They do not protect the employee if the employee fails to follow rules and procedures

• Examples– Policies and procedures for work practices– Training– Monitoring

6/27/2011 8

Administrative Controls-2Administrative Controls-2

• Dose = concentration x time– If the concentration of the chemical is

reduced, the dose or exposure will be reduced

– If the exposure time is reduced, the dose or exposure will also be reduced

6/27/2011 9

Personal Protective Equipment- PPE Personal Protective Equipment- PPE (1)(1)

• Last line of defenseLast line of defense– PPE does not reduce the hazard, it acts as a barrier between the

hazard and the worker

• Properly selected PPE must– Provide adequate protection– Be reasonably comfortable– Not get in the way of the employee

6/27/2011 10

• Remember: only the PPE stands between you and the hazard

• If the PPE is inappropriate for the hazard, not worn properly, or is damaged, the user will not be protected

PPE SelectionPPE Selection-11

• PPE selection must be based on the job to be performed– Too much PPE or inappropriate PPE can be

as dangerous as too little PPE– Doubling up 2 pairs of the wrong type of glove

will not improve protection

• Before performing a task, identify the hazards and type of PPE required to provide protection

6/27/2011 12

PPE Selection-2PPE Selection-2

• After selecting the level of protection, it is important to pick the proper type and size of PPE PPE is designed for specific uses with specific hazards Using PPE outside of manufacturer specifications will not protect

the user from hazards• Glove Selection

Latex gloves are not recommended for use with most

chemicals because of its short permeation rate. Nitrile

should be used when handling chemicals. Select the appropriate size Don’t use PPE that is too big too small

PPE usePPE use

• After selecting the appropriate PPE, it is important to know the proper way to use it– Read all instructions carefully– Ask questions if you are unsure of proper use– Inspect before each use

• Replace PPE often– Do not reuse disposable items– Decontaminate reusable items after use– Do not attempt to fix defective items

• Training is required before using PPE

PPE PPE for working in any room in Comparative Medicine Department (Animal Care)

• Hats, masks, shoe covers, gown, lab coat, safety glasses, gloves

Proper Glove RemovalProper Glove Removal

Step 1 Pinch center of one glove

Step 2Pull the glove half waydown hand

Step 3Remove glove on oppositehand by pinching the center asin Step 1 and pulling glove off

There is now one gloved hand and one bare hand

Step 4Using the bare hand, grab the inside of the glovewith index finger and remove

Step 5Both hands are now glove free, wash hands

Minimum RequirementsMinimum Requirements

• The following PPE is required for ALL work in the lab:• Gloves• Lab coat• Safety Glasses

– Contact EHS if you need glasses

• In addition to:– Close toed shoes – Long pants

• .

Other PPE includesOther PPE includes…..

• Hard hats

• Safety shoes

• Goggles

• Coveralls/ Gowns

• Face shields (for flying objects)

• Safety glasses (for splashes, dusts, optical; radiation)

• Masks (for dust or bedding from animal cages)

• Gloves (e.g. for handling cryogenics)

• Ear plugs (for high noise levels created from homogenizers, sonicators)

• Respirators (for mists, gases, vapors, smoke)

6/27/2011 21

RespiratorsRespirators

• Respirators Respirators may notmay not be be used under any used under any circumstances at NYMC circumstances at NYMC unless approved by EHS.unless approved by EHS.

• Contact EHS Contact EHS @ 594-4078@ 594-4078 for information

6/27/2011 22

TrainingTraining

• Employees must receive training / instruction specific to the PPE before use– Training is required by OSHA

• When PPE is necessary• What PPE is necessary• Limitations of the PPE• Inspections Procedures• How to properly put on, take off, adjust and

use• How to monitor while in use• Proper care, maintenance and useful life

• Additional training may be provided by your PI or Supervisor

• Respirator use requires NYMC authorization and a medical evaluation

6/27/2011 23

Remember…..Remember…..

• Always wear your PPE…!!!

6/27/2011 24

Summary Summary

• Where possible, hazards should first be reduced or eliminated through– Engineering Controls– Administrative Controls

• Conduct a Job Hazard Analysis to protect yourself– Use the Job Hazard Analysis to determine the proper

level of PPE

• Last but not least….– Use common sense and be safe!
