Key Learning Points from UCLA Accident -Researcher

• The lack of a lab coat – ( the single most significant factor in the severity of the burns that led to Sangji's death)

• She used plastic syringe, Sigma-Aldrich recommends using glass syringe for handling t-BuLi

• She was not prepared for a potential mishap, did no use the safety shower

• She was working alone• She had very little experience with the procedure and

she was making three times as much of the material as she had the previous time

88

Key Learning Points from UCLA Accident - Supervisor

• Training on handling hazardous chemicals and minimizing risk of exposure

• Record-keeping programsWhile Sangji was trained in general lab safety as well as the specific procedure she was performing, the training was not documented.

• Failure to ensure the use of personal protective equipment (PPE)

• Lack of SOP or procedures for the handling of pyrophorics such as the t-butyl lithium

What is a hazard? What is a risk?

24

What is a hazard? What is a risk?

Hazards are dangers intrinsic to a substance or operation;(anything that can cause harm, e.g. a chemical, electricity, radiation, ladder,)

Risk - the probability of injury associated with working with a substance or carrying out a particular laboratory operation; (i.e. the chance that someone will be harmed by the hazard)For a given chemical, risk can be reduced; hazard cannot.

2525

Hazard Control

2626

Key Learning Points from UCLA Accident

• The fundamental lab safety controls all fell short in this instance: – administrative (rules and policies),– engineering equipment (providing the right tools), – work practices – personal protective equipment

• The case emphasizes “the importance of developing not just a good training program, but a culture where people actually pay attention to safety – not just, ‘Yeah, I got my annual training and I’m done,’ and that’s it,”

2727

Hierarchy of Hazard Control

1.Eliminate the hazard

2. Substitute with a lesser hazard

3. Install engineering controls

4. Put administrative controls in place

5. Use personal protective equipment (PPE)

Hierarchy of controls (in order of preference)

28

PPE in the LabStandard PPE Not Acceptable

Biological Safety Cabinets (BSC)

Class II - primary containment device for work with biohazardous materials; protects: Personnel Product Environment Not designed for chemical use

5858

BSC vs Fumehood Can you use a BSC as a fumehood (ie to ventilate volatile chemicals?)

Can you use a fumehood as a BC? (ie to handle biological agents?)

5959

Biological Waste Laboratories must segregate biological waste

from other wastes

Containers provided by the CCC (yellow plastic bag and paper box)

Certain biological materials must be treated (usually by autoclaving) before entering the waste stream; You are responsible for autoclaving. (Autoclave training is required!)

Place the green label Treated Biological Materials before disposal in dumpsters

6060

Biological Waste Animal carcasses must be disposed of by incineration or other

methods. Contact the CCC for pick-up and disposal.

Sharps: puncture proof containers must be used (available from the CCC; pink), do not overfill.

Before disposal, sharps should not be: re-sheathed, broken, bent or otherwise manipulated

6969

Working in a Lab with Radioactive Materials

Training is mandatory if you will be handling RAM (online)

Only the RSO is authorized to order radioactive material

All radioactive materials must be secured to prevent theft or loss

Lost or theft must be reported to RSO All ionizing radiation areas MUST BE posted with

warning signs Use caution when entering and working in a

radiation area Follow standard lab rules

7070

Radiation Protection

Time: minimize the time that you are in contact with radioactive material

Distance: keep your distance. If you double the distance the exposure rate drops by factor of 4

Shielding: Lead, water, or concrete for gamma & X-ray, thick plastic for betas

7171

Radiation Monitoring Common type:

Thermoluminescence Detectors (TLD) used at UWindsor.

Used for x-ray and gamma rays, alpha and beta particles.

7272

Radioactive Waste Collect in appropriate radioactive waste containers and place in a

designated area; (behind Plexiglas shield) Appropriately labelled the waste Contact the HazMat Tech when ready to dispose of material

8/07/15

7373

X-ray Safety What is an X-Ray? Vs. other radiation sources? X-rays: safe when they are used properly (medical tests); can

be detrimental to human health when used improperly. The University X-Ray Safety Program (www.uwindsor.ca/ccc)

ensures compliance with regulations and facilitates research activity

X-ray warning signs MUST be posted. All X-ray rooms are restricted areas Personal dosimeter badges must be worn

7474

X-ray Crystallography Instrumentat UWindsor

7575

Laser Safety What is a laser?

Emits electromagnetic radiation: UV,VIS, IR

How do accidents occur? Refractive beams The human eyes are the primary organs of

concern. Skin to the lesser degree

7676

Class 3b and 4 lasers fall under the Laser Safety Program

Class 3b - From 5 mW to 500 mW -can easily cause eye injury from intrabeam or specular reflection viewing.

Class 4 - Above 500 mW - can cause eye injury from viewing diffuse reflections, skin injuries and ignite combustible materials in the beam path.

Laser Safety training along with site-specific hands-on training is mandatory

NMR Safety Main hazards: high magnetic fields, handling of cryogens high electrical voltages/RF sources

Spend no longer than necessary within the 5-Gauss zone

Keep metallic items at least 2-3 metres away from the magnet.

Person with medical implants (cardiac pacemakers, biostimulators etc.) MUST remain outside the NMR labs.

8686

NMR Safety

Be aware about the lab ventilation ( the He and N2 gas continuously exhausted by the instrument - install oxygen sensor alarm in the NMR lab)

Handle NMR tubes carefully and reserve them for NMR use only Report any accident to the NMR technician immediately

8787

Nanomaterials:Contain nanoparticles; often have unique optical, electronic, or mechanical properties. Hazard identification is still

difficult (no physical andchemical characteristics)

The potential adverse healtheffects are from inhalation,ingestion or dermal absorption

Precautionary approach shouldbe taken to the risk management

SiC nanopowder is nano-sized SiC super fine powder. Nano-size means nano-meter, which equals 10-9 meters (parts per billion meters = parts per million millimeters)
