Consolidate the list and create a
Hazardous Substance Register
of all potentially hazardous substances on
board. Consideration
should
also be given to substances arising from the work process (e.g. welding fumes
or disturbance of insulation material), cargo back load, etc.
The
Hazardous Substance Register
shall
contain the list of all hazardous substances and all relevant
Material Safety Data Sheets (MSDS).
The list
should
contain:
x
The product name;
x
Quantity;
x
Location;
x
MSDS issue date, number and location;
x
Potential hazards;
x
Control methods.
Vessels
shall
create and maintain their own
Hazardous Substance Register
following this procedure.
Ensure all employees have ready access to the register for all the hazardous substances they use or to
which they may be exposed.
Labels
The initial source of information for most users is the label on the container. Therefore it is vital that
containers of hazardous substances are comprehensively labelled, showing the unique identification of the
substance
product name and general nature of the hazards (i.e. a dangerous goods class diamond or
poisons cautionary statement.)

MSDS
More detailed information on hazardous substances may be obtained in an appropriate format from MSDS
supplied by the manufacturer, importer or supplier.
The MSDS
shall
provide information on:
x
Product name;
x
Physical description and properties;
x
Uses;
x
Composition;
x
Health hazards;
x
How to clean up if spilled;
x
Correct first aid treatment;
x
Handling storage;
x
Exposure controls/PPE;
x
Fire Fighting measures;
x
Ecological information.
Employees
should
ensure that they have read and understood the contents of the products MSDS prior to
handling/using the product. MSDS
should
be available at the storage location as well as in the register.
Step 3
Assess the Substance
When assessing the risks that may result from exposure to any substance it is necessary to determine if the
substance is hazardous (i.e. does it present a hazard to the worker?) and what control methods may be
required.
All factors in a risk assessment are interconnected. They
should
be considered in isolation and then for their
combined effect.
The factors are:
