ENVIRONMENTAL HEALTH AND SAFETY MANAGEMENT SYSTEM

The Internal Responsibilty System (IRS) is basis of the Occupational Health and Safety Act

The University has a primary duty under OHSA:

DUTIES AND PRECAUTIONSEmployers' precautions and duties


13 (1) Every employer shall take every precaution that is reasonable in the circumstances to ensure thehealth and safety of persons at or near the workplace”

Implicit in legislation and its interpretation by the Supreme Court of Canada

•an employer has a positive duty to

•put in place a proper system to prevent the occurrence of offenses under the Act

•take reasonable steps to ensure the effective operation of that system


Employees’ Rights


• Three basic rights under the Occupational Health and Safety Act

1. Right to Participate

2. Right to Know

3. Right to Refuse Unsafe Work


Joint Health and Safety Committees (JHSC)

• Required by the Occupational Health and Safety

Act where there are 20 or more employees

• Made up of worker and management employees


who meet regularly to discuss health and safety

issues in the workplace

– Identify hazards

– Perform regular inspections

– Make recommendations to improve health and safety

– Investigate serious accidents

– Investigate work refusals


Reporting Health and Safety Concerns

You have a few options:

• Discuss the matter with your immediate supervisor

• Request your Joint Health and Safety Committee to investigate the

concern


• Contact the Office of Environmental Health and Safety for advice or assistance in addressing concerns (Local 2495)




SPECIALIST COMMITTEES

• internal committees control and regulate the use of specific hazardous agents

– DALHOUSIEUNIVERSITYRadiation Safety Committee

– DALHOUSIEUNIVERSITYBiosafety Committee

– DALHOUSIEUNIVERSITYChemical Safety Committee


– DALHOUSIEUNIVERSITYEnvironmental Protection Committee

• Radiation Safety Committee has executive authority for radiation protection

• Chair of the Radiation Safety Cttee or delegate sits on JHSCttee

• Biosafety Committee has executive authority for biohazard protection

• Chair of Biosafety Committee or delegate sits on JHSCttee




Chemical Hazards

• Be familiar with hazards and precautions associatedwith the chemicals you use.

– Workplace Hazardous Materials InformationSystem (WHMIS) training

– Reading current Material Safety Data Sheets(MSDS)


– , ,

– Learn to use proper engineering controls (e.g.fume hoods)

– Learn to use personal protective equipmentproperly

– Follow appropriate emergency procedures


Biological Hazards


• Bacteria, viruses, fungi, parasites, animal cells and their toxins

• Biosafety Certificate required for all activities using biological agents

• Labs that use higher-risk biologicals must have a biohazard sign on the door


Ionizing Radiation Hazards

• Radioisotopes, irradiators and x-ray devices used across campus

• Strict requirements are in place to control exposures to radioactive sources

• Radiation Safety routinely monitors labs for compliance with University policies andre ulations


• Recognize the radiation material symbol and take appropriate precautions

• Contact Radiation Safety at 902-494-2495 for more information or the Office of Environmental Health and Safety’s website

RADIATIONSYMBOL


Non-Ionizing Radiation Hazards

• Exposure to various forms of non-ionizingradiation must be below allowable levels

– Electromagnetic fields

– Lasers

– Microwaves


– Radiofrequency

– Infrared / ultraviolet / visible light

• Laser users must be registered by theLaser Safety Officer


Ergonomic Hazards

• Risk of repetitive strain injury or other discomfortreduced with appropriate office furniture

• Ergonomic tips available on Office of EnvironmentalHealth and Safet ’s website


• Contact Occupational Hygiene and Safety Services at902-494-2495 for more information


Emergency Response


• Be prepared for an emergency!

• Know where emergency equipment are located, and how to use them: – Fire extinguishers

– Chemical spill kits

– Safety showers, eyewash stations

– First aid kits

• Emergency Contact 4109




Working Alone Service

University Police provide a Working Alone/WalkSafe Service

Visiting / telephoning you

Contacting you in event of emergency in your area


o owng up una e o ma e conac

Tiger Patrol

Emergency 4109


Occupational Health Service


• Occupational Health Nurse/Physician being considered – Occupational disease prevention, health risk assessments, medical surveillance

and immunization, hearing tests, spirometry

• Contact 902-494-2495 for more information




• Students on leaving the University should take with them an attitude of mind whichaccepts good health and safety practice as normal

• University staff set a high standard by personal example


• Common misperceptions• safety is just common sense

• most accidents are caused by unsafe actions by the injured person

In fact, accidents generally arise from failures in control, often have multiple causes

Causes lie not with "careless workers", but organizational mgmt failings or oversights

Sample Procedure for LI FEPAK® CR Plus Automated

External Defibrillator (AED) (semiautomatic model)

NOTE: If AED is not immediately available, perform CPR until AED arrives on the scene.

Assess scene for safety.

• Determine unresponsiveness.

• Activate system Dial 41 09 (494-41 09)• Open airway (A).

• Check for breathing (B)-if not breathing, or if breathlng is ineffective, give two slow breaths.

• Check for signs of circulation, such as pulse and coughing, or movement (C).

• If no signs of circulation, apply AED immediately.

• Press the LID RELEASE/ON-OFF button to open the lid; this turns on the AED. Follow voice prompts. Do not touch

the victim unless instructed to do so.

• Follow voice prompts to apply electrode pads. Shave chest hair (if it is so excessive it prevents a good seal between

electrodes and skin). If the Victim's chest is dirty or wet, wipe the chest clean and dry.

• Stand clear of victim while machine evaluates victim's heart rhythm.

SHOCK ADVISED:• Clear area, make sure no one is touching the victim. Push SHOCK button when instructed. Device will evaluate the

victim's heart rhythm and shockup to three times. After three shocks device will prompt to check pulse (or for

breathing or signs of circulation) and if absent, start CPR. If pulse or signs of circulation such as nonnal breathing

and movement are absent, perform CPR for one minute. Device will countdown one minute of CPR and will auto

matically re-evaluate victim's heart rhythm when CPR time is over.

NO SHOCK ADVISED: "

• Device will prompt to check pulse (or for breathing or signs of circulation) and if absent, startCPR. If pulse or signs

of circulation such as nonnal breathing and movement are absent, perform CPR for one minute. If pulse or signs

of circulation such as breathing and movement are present, check for normal breathlng. If victim is not breathing

normally, give rescue breaths at a rate of 12 per minute. AED will automatically evaluate victim's heart rhythm after

one minute.

• Continue cycles of heart rhythm evaluations, shocks (if advised) and CPR until professional help arrives. Victim must

be transported to hospital. Leave AED attached to victim until EMS arrives and disconnects AED.

AFTER USE:• AED data will be downloaded within 24 hours (weekdays) with copies sent to: EMS, authorizing physician and envi

ronmental health department. .

• the AED will be wiped clean according to policy.

• Both the QUIK-PAKTM electrode packet and the CHARGE-PAKTM battery charger must be replaced after every use.

• Contents of attached resuscitation kit must be replaced if used.

THE SAFE ZONE

THE ABC's OF .PORTABLE FIRE EXTINGUISHERS

Type A Extinguishers

Used on type A fires involving ordinary combustibles such aswood, paper, clothing, fabrics, most plastics and rubber.

Type '8 Extinguishers

Used on type B flammable liquid fires. Included are liquidssuch as gasoline, many paints, cooking oil and other oils.Using water on a type B fire could cause the burning liquid tospread to other areas and ignite other nearby combustiblematerials.

Type C Extinguishers

Used on type C electrical fires including fires in energizedelectrical equipment such as fuse boxes, power bars, motorsand other pieces of electrically energized equipment. Using

the wrong extinguisher on an electrical fire presents anelectrocution risk.

Type D Extinguishers

Type 0 extinguishers are special extinguishers used on

burning metals such as sodium or magnesium. They arefound only in metal working shops and some hazardousmaterial storerooms.

CLASS A Silver extinguishers containing water under pressure.

CLASS BC

CLASS ABC

Red extinguishers with a black flexible hose connected to a largediameter black "horn" or nozzle. These extinguishers containpressurized carbon dioxide which, when released, deprives a fireof oxygen. The carbon dioxide from a BC extinguisher is.verycold . Be careful not to allow the cold gas or chilled metal parts tocontact the skin.

Red or red-orange extinguishers which have a black

hose rather than a "horn". VVhen discharged, ABCextinguishers release a solid powder which smothers aflame.

FIGHT A SMALL FIRE:

1. SOUND THE ALARM to begin the building evacuation.2 . CHOOSE THE CORRECT EXTINGUISHER for the type of ire.3. MAKE SURE YOU ALWAYS HAVE A SAFE ESCAPE ROUTE.

4. GET AS CLOSE AS YOU CAN TO THE FIRE.

PULL the pin that will release the handle. AIM the extinguisher nozzle at the base of the fire.

SQUEEZE the handle.

SWEEP the nozzle from side to side moving forward as you extinguish theflames.

5. WATCH that the fire does not re-ignite from a hot spot.

THESAFE ZONE

BASIC COMPRESSED GAS SAFETY

USING COMPRESSED GASES:

1. Limit quantities of compressed gases present in the laboratory. Ensure that cylinders are always labelled

2. Treat all cylinders as full. Keep them in the upright position, secured to a wall or bench.

3. Never allow a cylinder to fall or bang against another cylinder.

4. Position the cylinder so you can easily reach the cylinder valve and regulator.

5. Select the correct regulator for the gas. Never adapt a

regulator designed for use with a different gas.

6. Use only manufacturer approved regulator lubricants.

Under pressure, gases such as oxygen, react dangerously

with oil or grease lubricants.

7. Ground all flammable gas cylinders.

8. Only use the regulator to control pressure. Do not try to control flow rate with a regulator alone.

9. Check distribution system for leaks daily. A 50% glycerine/water or a soap solution works well except with

oxidizing gases.

10. Never transfer gases between cylinders.

11. Do not pressurize glass equipment.

12. When gas will not be used for several days, remove the regulator and replace the cylinder cap.

13. Do not completely drain high pressure cylinders. When pressure falls to 30 psi, discontinue use, close value,

remove regulator, replace cap, mark “MT” and return cylinder to supplier.

THE SAFE ZONE CONTINUED . . .

STORING COMPRESSED GASES:

1. Store compressed gas cylinders in the upright position, secured to

a wall or a bench.

2. Do not store cylinders - even empty ones - in corridors

or stairwells.

3. Store cylinders in a fire-resistant, well-ventilated area,

away from sources of heat and out of direct sunlight. Protect

from temperatures above 30

o

C.

4. Store gases which support combustion (i.e. oxygen, fluorine,

chlorine) well away from fuel gases (i.e. hydrogen, methane,

carbon monoxide).

5. If possible, store flammable gases outdoors, connected to a

piped distribution system.

TRANSPORTING COMPRESSED GASES:

- Within Dalhousie Buildings

1. Always use a cylinder cart to move cylinders.

Chain cylinder to the cart.

2. Ensure that the cylinder cap is in place before

moving a cylinder.

- Off-Campus

1. Do not transport compressed gases on public roads

without Safety Office authorization.

2. Do not move compressed gases in closed vehicles.

3. Secure cylinders in the upright position.

TOOLSHand tools are designed to do a particular job. Using the wrong tool orusing the tool improperly, can damage the tool, the work, or even cause

an injury.

Before You Start

• Don't work alone.

• Dress properly to reduce the chances of an entanglement injury. Keep long hair

tied back and sleeve cuffs buttoned. Don't wear loose clothing.

• Don't service electrically energized equipment. Disconnect the power cord orshut o ff the circuit breaker.

• Check materials for defects. Check wood for knots, nails or staples. Checkmetal pieces for burrs.

Choose the Correct Tool

• Metal snips are designed to make either straight cuts or to cut to the left or right.

• Hand saws are made for ripping or cutting across the wood grain.

• Different types of hammer and mallets are not interchangeable.

• Don't use screw drivers or knives when you need a pry tool.

• Don't use pliers when you need a wrench.

• Don't use chisels to remove paint or as a replacement for a screwdriver.

Choose Ergonomically Designed Tools to Reduce the Likelihood of Injury

• Select hammers that are designed to protect your wrist from harmful shock andvibration.

• Choose saws and similar tools that don't require you to bend your wrist.

• Look for tools, such as pliers and cutters, that are sized to your hand.

• Select ratchet-type tools to reduce the injury that can result from repetitiveforceful wrist movements.

THE ZONE CONTINUED . . .AFEUse Tools Properly

• Don't use damaged tools. Don't use striking tools (such as hammer or cold

chisels) if the head is cracked or "mushroomed". Don't use tools with cracked orloose handles.

• Don't use excessive force. The need for excessive force probably means youare using the wrong tool. Don't strike the handle of a wrench with a hammer tofree a tight nut. Get a longer wrench or use penetrating oil.

• Secure the work piece. Use a clamp or a vice if necessary.

• Use a hammer so that the striking face is parallel to the surface being struck toavoid the hammer glancing off the target. causing injury. Don't hit one hammerwith another.

• Use hand saws properly. Apply pressure on the downward stroke. Keep ripsaws at a 60 degree angle to the wood. Use cross cut saws at a 45 degreeangle.

• Don't cut towards your body unless you are using a tool such as a draw knifespecially designed for that use.

• Install the blade of a hacksaw with the teeth pointing forward. Keep the bladetight and frame of the saw properly aligned while you cut.

• Be conscious of the risk of fire when using soldering irons or other hot tools.Keep flammables away and unplug the tool immediately after you have finishedusing It.

• Keep cutting tools sharp. Sharp tools work better and you are less likely toinjure yourself with a sharp tool than with a dull one.

• Never carry sharp or pointed tools in your pocket. Use a tool belt.

Store Tools Properly

• When possible, use a tool rack.

• Prevent rust. Lightly oil tools that will be stored for extended periods.

• Store knives and other sharp tools in a way which doesn't damage the blade.

Use Protective Equipment

• Wear safety eye wear and safety shoes whenever you are working with tools.

• Wear gloves when working with rough materials or to prevent cut or punctureinjuries.

• Wear hearing protection in noisy situations.

• Wear a mask when working in dusty situations or when exposed to chemical fumes.
