Requirements to Undertake A Risk
Assessment
This booklet has been prepared to assist the
woodworking industry comply with their obligations
under the Occupational Health & Safety (Hazardous
Substances) Regulations 1999. These regulations
require employers, in consultation with employees to:

make a list of hazardous substances in the
workplace (ie compile a register)

obtain current manufacturers/importers’ MSDS for
each product and put copy in the register

ensure MSDS are accessible to employees

identify hazardous substances in systems such as
pipes, process vessels, reactor vessels or
equipment involved in a manufacturing process to
employees who may be exposed to them (where
applicable)

undertake a risk assessment for all hazardous
substances in use as well as for any new
substance

revise risk assessments if conditions change and in
any event, every 5 years

undertake specific measures to control risk

ensure risk control (safety) measures are properly
used and maintained

ensure exposure standards are not exceeded

undertake atmospheric monitoring and health
surveillance if required

keep various records

provide information, instruction and training to
employees

consult health and safety representatives
In order to fulfill these obligations employers should first
prepare a Register of Hazardous Substances. An
example of such a register is incorporated in this
document.
Employers should be able to demonstrate they have
carefully considered the questions raised in this booklet
and have taken all reason steps to minimise worker
exposures to substances used in the workplace.
Evidence of consultation with OH&S representatives
and the workforce is also required. The benefit of
consultation with employees is that actual work
practices will be reviewed as part of this risk

How to Use This Booklet

Using the flow chart on the opposite page employers
should be able to achieve compliance with the
regulations.

……………………………………………………………..
Employers should note, the questions are generic to
many of the substances and processes used in the
industry but may not cover every process or chemical
used in the industry.
Where other processes or hazardous substances are
used, a risk assessment will need to be undertaken
based on the hazards posed by the chemicals used in
these additional processes (refer Appendix A for risk
assessment template)
The use of this booklet will enable workplace
representatives to perform risk assessments on the
following processes:

Mixing & Decanting Solvents
1.0 Mixing & Decanting Locations
A range of solvents stored in tins and bottles may be
decanted and mixed on site. The majority of these
solvents are associated with lacquer paints, varnishes
and stains used to finish wood products. These
chemicals are flammable and may be manually mixed
and applied utilising spray application. Exposure to
these products is generally through skin contact and
inhalation of solvent vapours and fine spray mists. The
solvents may be highly irritating to the eyes, skin and
respiratory system and may cause central nervous
system depression and headache after prolonged
exposure.
List possible health hazards which may result from
using these products:
___________________________________________
Are designated areas assigned for
mixing/decanting solvents?

stored solvents?

1.0 Evidence of Exposure
A range of timber and veneered products are utilised
throughout wood working processes. These include
soft and hardwoods as well as medium density
fibreboards. Wood dust is not classified as a hazardous
substance, however, certain hardwoods such as beech
and oak may produce allergic asthma like respiratory
sensitisation after repeated or prolonged exposure to
their dust. Chemical constituents such as
formaldehyde may also be released in dust produced
through the use of mechanical equipment in the
cutting/sanding/routing of MDF.

Adhesives Application

A variety of woodworking adhesives are utilised in the
manufacture of products. These include single part
adhesives and two part resins with hardeners. These
materials are irritants to the skin, respiratory system
and eyes and may also cause sensitisation upon
prolonged or repeated contact.
Does the form or concentration of the
substance differ from that described
above?
A range of catalysts are also available for efficient
curing of adhesives. These catalysts may be acidic
compounds such as toluene-4-sulfonic acid or skin and
eye irritants such as ammonium chloride. Adhesive
thinners are also used to remove excess adhesive from
surfaces. These thinners are highly flammable and
contain volatile components such as toluene, xylene or
methyl ethyl ketone. These chemicals may cause
irritation, coughing or headache through repeated
inhalation of vapours with exposures increased through
chemical absorption through the skin.

using these products:

areas?
If YES to any of the above, additional safety measures
may be necessary to reduce the risk of exposure.
In addition to these effects, acrylic urethanes may
contain isocyanates (refer to next section for risk
assessment) that have the potential to cause contact
dermatitis and respiratory sensitisation in susceptible
individuals. The use of thinning chemicals for spray
applications and in cleaning processes also presents
similar irritant health effects and central nervous
system depression as for stains and paints.

1.0 Mixing and Decanting
Isocyanate based products are highly irritating to the
eyes, throat and respiratory system and may cause
symptoms such as watering eyes, dryness of the
throat, headaches and tightness of the chest. These
symptoms may occur immediately upon exposure or
some hours after. Isocyanate based products may
induce respiratory sensitisation that produces asthmalike symptoms in susceptible individuals when exposed
to only minor quantities of the chemical substance.
There is also a potential for the onset of contact
dermatitis after prolonged use of the product.

Cleaning and Waste Removal
Various cleaning methods will be employed in
workplaces to ensure working surfaces are maintained
in optimal condition. Cleaning methods utilised for
removing wood shavings may include dry sweeping,
vacuuming or even the use of compressed air. Some
of these methods (ie compressed air) may be more
detrimental to health and the workplace than beneficial.
Cleaning may also involve the use of solvents.

Are solvents used to clean paints or

Are solvents used to clean work

times?
If YES to any of the above, additional safety measures
may be required.
Waste removal is an important component of the
cleaning process as there will often be a requirement
for used solvents to be removed from site. In addition
to this, there may also be a requirement to remove
wood dusts accumulated from site exhaust ventilation.
These processes may further expose personnel to
hazardous substances in both the cleaning and
removal processes.
