THE UNIVERSITY IS CLOSED BETWEEN MIDNIGHT AND 6AM

Work in the School is classed into three categories:

LOW RISK Office work and taking measurements from machines such as UV, IR, NMR

HIGH RISK Any work with hazardous, toxic or corrosive chemicals - virtually all laboratory work is falls under this category

EXTREME RISK carcinogens, explosives, radioactive material or highly toxic chemicals. eg. CO, HF, any experiment that would need immediate medical treatment if something goes wrong

The School has the following COMPULSORY time schedule(availability of first aiders, fire wardens, access to building etc)

LOW 6am-12am, Mon-Sun

HIGH 7am to 10pm, Mon-Sun

EXTREME 9am-5pm, Mon-Fri ONLY

Lab Managers and Persons-in-charge lists

All work above low risk must have another adequately trained person within audible distance to assist. At LEAST ONE person present must be on the Lab Managers/Person-in-Charge list

All staff and PhD students, but not MSc, Honours or PgDipSci students will be on the list

Working alone in labs IS PROHIBITED. There must be someone in the vicinity if you are working alone in a lab. This person must be able to see and hear you (and vice versa).

At any one time there is only ever ONE person in charge of the laboratory

A hierarchical system exists where the Lab Manager is responsible for all activities undertaken in the laboratory. If the Lab Manager is absent then the responsibility falls to the next person on the list and so on.

1 ..they are wearing appropriate personal protection

2 ..that chemicals are transported in a safe manner

3 ..the safe storage of chemicals

4 ..the correct usage of chemicals

5 ..the appropriate disposal of chemical and physical waste

6 ..they know what to do in case of an accident or emergency (and act accordingly)

All researchers are required to ensure..

For all commercially available chemicals 2-6 can be determined by reading the Material Safety Data Sheet (MSDS) for that chemical

Laboratory managers are EXPECTED to enforce points 1-6

1. Personal Protection and Safety Equipment

Know the location of and familiarize yourself with all the safety equipment in your laboratory:

• Fire extinguishers• Fire hoses• Fire alarms

• Emergency exits• Eye wash stations

• Safety showers• First Aid kits (Diphoterine)• Spill kits and sand buckets

• Breathing apparatus• Telephones and emergency numbers:

Emergency services (1-111) and/or UniSafe (966)

8

Clothing and footwear• Protective clothing MUST be worn in labs AT ALL TIMES• Laboratory coat, safety glasses and covered shoes are the minimum standard for laboratory work• Tie back long hair • No headphones• Laboratory coats must be removed when going from labs to office areas

9

Safety Glasses• Safety glasses must be worn at all times in laboratory areas

• Prescription glasses DO NOT constitute safety glasses and provide no protection from chemical splashes coming from the sides

• All PhD students with PRESS accounts are eligible to obtain prescription safety glasses from the UoA Optometry clinic, the form is available on the website.

UCLA's Molecular Sciences Building was closed for the holidays on Dec. 29 as research assistant Sheri Sangji worked on an organic chemistry experiment

Only three months into her job in the lab, the 23-year-old was using a plastic syringe to extract a small quantity of t-butyllithium -- a chemical compound that ignites instantly when exposed to air

As she withdrew the liquid, the syringe came apart in her hands. A flash fire set her clothing ablaze and spread second- and third-degree burns over 43% of her body.

Eighteen days later, Sheri died in a hospital burns unit.

Records show all that stood between her torso and the fire that engulfed her was a highly flammable, synthetic sweater

No labcoat

In the lab alone

Did not know the location of the safety shower

2. Transportation Between Campuses

• All chemicals needed at Tamaki should be delivered directly to Tamaki to avoid

secondary transport.

• Transport of chemicals is regulated by the Land Transport Rule: Dangerous Goods

1999

• Failure to observe these regulations will entail prosecution

Fines start at >$1000 for the individual, >$5000 for the university

• Public transport, including the inter-campus bus CANNOT be used to transport

any chemical or dangerous good, no matter how small

• CHEMCOURIERS – Fully licensed and $15 per package

13

3. STORAGE• Appropriate labelling – ALL CHEMICALS must be labeled with as much detail as possible, including research samples. A minimum label is a lab book reference.

• All large samples (>50g) should display complete safety information (eg: decanting)

• All chemicals (no matter how few and in all locations) must be segregated by hazard class

• All labs in SCS have designated chemical storage areas

• Check the MSDS for storage details and if in any doubt consult the lab technician or your supervisor

14

4. EXPERIMENTS• Consult your supervisor when designing an experiment to ensure what you are doing is safe and appropriate. Think through what you are doing

PERFORM A TAKE 5 ASSESSMENT BEFORE EVERY EXPERIMENT

• Read the MSDS information on all chemicals

• Know the location of safety items that may be required (eg. Sand buckets, powder extinguishers, calcium gluconate for HF, antidote for cyanide...)

• Think about any changes to the experiment

• ALWAYS use a fumehood. Report any faulty fumehoods IMMEDIATELY

• If you leave the experiment AT ANY TIME, inform all lab occupants of correct procedure if an accident was to occur. Use the yellow unattended experiment forms.

15

OVERNIGHT / UNATTENDED EXPERIMENT FORMS

• MUST be filled out for ALL experiments that are left overnight or unattended for significant periods

•Filled out by the experimenter and signed by your supervisor or a delegated person in charge (Postdoc, senior PhD)

• The person signing the form must inspect the reaction setup before signing the form

• Attach the signed and completed form next to the experiment

• Forms are laminated - easily wiped clean and re-used

16

Overnight / unattended experiments

5. WASTE DISPOSAL• All hazardous waste must be taken to the STORES where it will be removed by a chemical contractor

• NEVER put chemical waste in the normal rubbish bins

All other waste must be appropriately segregated, clearly labeled and submitted to stores for disposal

• Waste solvent in chlorinated or non-chlorinated bottles ---> STORES

• NEVER MIX ORGANIC (SOLVENTS) AND AQUEOUS WASTE

• DO NOT MIX CHLORINATED AND NON-CHLORINATED WASTE

• ALL chemical waste disposed via STORES must be clearly LABELLED

What can go down the drains?

• Only water miscible, non-toxic chemicals in small (~100mL) quantities

• The School’s waste water is monitored17

6. Accidents and Spills

SPILLS – you MUST know what to do for each chemical BEFORE you use it. READ

the MSDS before use and fill out a Take 5 assessment. Consider:

• Quantity, volatility, ventilation, toxicity, flammability

• Suitable absorbents, neutralizers and waste containers - LOCATION

• Warn others if required and ensure help is available (YELLOW FORMS)

All labs conducting wet chemistry have large spill kits (inform me if any do not)

In the event of a large (> 10 L) organic solvent spill

• immediately evacuate the area and inform a member of Staff

• if no Staff member is immediately available, trigger the fire alarm and Dial 111

NEVER tackle a large spill on your own

22

Accidents and Spills - REPORTING

• ALL accidents and incidents in the School must be reported to the School

Manager using an accident/incident report form.

•Should the incident have potentially dangerous ramifications, then an incident

investigation report must also be filed. All forms are available from David Ware,

Mike Wadsworth and the School website (occupational H&S section).

• When serious injury or major incident occurs, the accident site must be secured

pending investigation

Reporting potential accidents• Should you become aware of dangerous situations, do not hesitate to report it to

your research supervisor, the H&S coordinator, the School Manager or the Head of

School. Don’t wait for an accident to happen!

23

FIRST AID

Lists of Staff/students with First Aid certificates are located near all First Aid cabinets

First Aid boxes are housed throughout laboratories.

First aid cabinets are located in the corridor leading to the Goods Lift on Floors 5, 6 and 7.

Diphoterine - use immediately on any chemical burn (solvent, acid, base but not HF). Use in eyes. Ask your supervisor where it is kept in your laboratory.

For serious incidents, DIAL 1-111 and request an ambulance

If emergency is related to a chemical provide a hard copy of the MSDS to accompany the victim to hospital

If you suffer from any medical condition please inform me and your supervisor/lab colleagues so appropriate precautions can be put in place (Diabetic, allergies etc)

24

• Fire extinguishers are placed throughout the School - Familiarise yourself with their location

• Only every attempt to tackle small fires. If no progress diminishing the size of the fire is being made after 20 seconds immediately leave the area and trigger the alarm. Dial 1-111

• Exit the building using the stairwell NOT the lifts. Don’t run.

• If the incident occurred in your lab area, proceed to the front of building 301 and provide the fire wardens and emergency services with as much information as possible

• Consider the building work going on! (take care in staircases etc)
