Health, Safety & Environment General Awareness Training
work place and environment.
Nanotechnology is a rapidly growing field that has the potential to offer significant advances to society. Like any new technology, we need to ensure we have an adequate understanding of any relevant Health, Safety, and Environmental issues so we can ensure on-going safety.

Naturally occurring nanoparticles have been around for a
long time. Engineered nanoparticles are relatively new and
potential applications across a range of industries.
Small size = Improved delivery of drugs to specific sites.
= Lower cost and more powerful micro electronic devices.
High surface area
= More efficient energy storage – batteries, capacitors, fuel cells.
= More efficient automobile catalytic converters.
Opacity = Protective and glare reducing coatings.
Nano technology has a wide variety of applications that could improve people’s lives.
The next 3 slides will address the potential health effects of nanotechnology
2. For individual nano receipts health effects
will depend on things like:
We will know enough to understand how to protect you in your particular situation.
regular size parent materials.
The next 2 slides deal with other workplace safety hazards in addition to health
There are other possible work place safety hazards in addition to health:
1. Organic & metal dusts may present explosion / fire hazards.
- Explosion venting.
- Strong materials of construction.
- Pressure transducers to detect pressure rise followed by rapid deluging.
- Supplying an inert atmosphere.
Due to small size and large surface area the risk for fire and explosion
may be higher than for regular sized particles. However:
Dust explosion/ fire is a risk we know how to manage. Your HS&E resources can advise you.
remove nanoparticles from air streams.
by incineration or fixing them in concrete / cement.
disposal on a case by case basis.
Perform a risk assessment before starting any work with nanotechnology. Involve your site HS&E & Medical resources.
The risk assessment will identify appropriate controls and work
practices for your specific application.

Steps to decide how to dispose of wastes containing nanoparticles.
For bench scale work dispose of liquid and solid wastes containing
Nano materials as if they were hazardous wastes.
For Pilot and large scale work seek input from a professional HS&E resource.
Consult with an Occupational Medicine doctor.
Create a culture whereby health & safety considerations are built into the work from the start:
