8. NFPA 704
NFPA 704 is a standard maintained by the US-based
National Fire Protection Association. It defines the
colloquial "fire diamond" used by emergency
personnel to quickly and easily identify the risks
posed by nearby hazardous materials. This is
necessary to help determine what, if any, special
equipment should be used, procedures followed, or
precautions taken during the first moments of an
emergency response.

regardingthepropertiesofaparticularsubstance.
MSDS includes information such as physical data
(melting point, boiling point, flash point etc. ) ,
toxicity, health effects, first aid, reactivity, storage,
disposal, personal protective equipment, and spill-
handling procedures. MSDS formats can vary from
source to source within a country depending on
national requirements.

14. Read the Label

16. Hazardous materials must be stored in a
manner that adequately protects both human
health and the environment from unintended
exposure to the primary hazards associated with
the materials. These primary hazards may
include explosion, fire, reactivity, toxicity or any
combination of these hazards.
Storage of Hazardous Materials

17. Criteria for suitable storage areas include:
Located away from high traffic areas on site and reasonably protected from the potential
for vehicle/equipment damage by guardrails, fences, or other structural controls
Provided with a means to control access to the materials so that only authorized (e.g.,
trained) personnel may remove and use the materials
Located away from fence line locations immediately adjacent to environmentally sensitive
resources (e.g., wetlands, streams, archeological sites)
Provided with adequate secondary containment in the form of an impermeable surface
surround by curbing or equivalent means to minimize the release of accidentally spilled
product to the environment
Provided with a means of segregating combustible and flammable materials form
oxidizing agents and other sources of ignition
Provided with a means of preventing water reactive and pyrophoric materials (examples
phosphorus, iron sulfide etc) from coming in contact with accumulated water

ResponseTeam
A spill response team shall be developed within each Contractor
organization to act as the immediate first response measure in the
event of a spill. Contractor personnel shall be trained to respond to
environmental releases, and shall be knowledgeable of the locations
of spill response equipment and materials and their use and
disposal options.
Spill Response and Clean up Procedures

19. Response Action
►If spilled materials are flammable, eliminate potential sources of ignition from within and
near the spill area.
►IF IT CAN BE PERFORMED SAFELY , stop the source of the spill, seal off the drains
that the spill may reach, and contain the spill within as small an area as possible.
►If the personnel experiencing the spill requires emergency assistance, the following
Emergency Services shall be contacted:
•NCC ES&H Lead: TBT
•Project Emergency Services.
►Secure the area, warn other personnel to stay away from the area, establish perimeter
control at a safe distance from the spill, and immediately notify the SM.
►Scene management is the responsibility of the NCC SM, or their designee, until
Emergency Services personnel assume control (if necessary).
►Notify Employer as required.

20. Clean Up Actions for Spills of Petroleum Products
SAFETY FIRST
•Avoid inhalation of vapours by staying upwind or use proper respiratory protection.
•Use chemical-resistant personal protective equipment (PPE) during clean up activities.
•Gasoline and gasoline vapours are HIGHLY FLAMMABLE and may create an explosive
atmosphere -remove sources of heat, sparks, flame, friction, and electricity; restrict fires
or open flames from the spill area.
IF IT CAN BE PERFORMED SAFELY, the NCC SM will supervise the clean up of
spilled material and equipment.
Small spills, including leaks from equipment, should be cleaned-up immediately with
absorbents and clean up materials properly labelled and disposed.
Large spills outside of contained areas should be diked with absorbent or soil to prevent
liquids from reaching drainages, storm drains. Clean up decisions for large amounts of
free liquids will be made in conjunction with the SM or designee. Clean up may be
performed by a third party trained and licensed hazardous materials response contractor.

21. Spill clean up wastes must be placed in appropriate waste containers,
properly labelled, and stored in a designated hazardous waste storage area
prior to disposal. Cleanup waste shall be disposed of as hazardous waste.
Diesel fuel, gasoline, and hydraulic/lube oil cleanup wastes that contain
free-flowing liquid should be drained to remove as much of the free-
flowing product as possible. The remaining sludge / solids must be
properly labelled and disposed of as hazardous waste.
The free product removed from the waste and all gasoline spill waste must
either be recycled or, if not recyclable, disposed of as a hazardous waste.

22. Clean Up Actions for Chemical Spills
SAFETY FIRST
•Avoid inhalation of vapours by staying upwind or use proper respiratory protection.
•Use chemical-resistant PPE during clean up activities.
•Restrict fires or open flames from the spill area.
•Personnel not trained to deal with chemicals shall not attempt to clean up spill.
•Refer to the MSDS for special hazards associated with any spilled chemicals, especially for
reactivity with other materials in the spilled area.
Small spills within contained areas should be neutralized (if appropriate). Free product that
cannot be used must be classified as to whether it is a hazardous waste.
Spills of caustics or other highly volatile or dangerous chemicals outside contained areas
should be diked with absorbent or soil to prevent liquids from reaching drainages, storm
sewers. Clean up decisions for large amounts of free liquids will be made in conjunction with
the external Emergency Services.
Spill cleanup wastes must be placed in suitable containers, labelled and transferred to a
designated hazardous waste storage area.

23. Hazardous wastes and used oil will only be stored in areas designed to
ensure non-compatible wastes are segregated and located in designated
areas to optimize control.
Containers of material without a label shall be treated as hazardous waste
until the material has been identified and proven to be non-hazardous.
Containers of unknown material assumed to be hazardous will be labelled
“UNKNOWN SUBSTANCE –Do not use.
Maintenance waste (e.g., batteries, waste oils, oily rags) generated in work
areas will be temporarily stored in appropriate hazardous waste storage
containers until the waste can be transported to the approved hazardous
waste storage area. Under no conditions will hazardous waste be stored at
work areas without being stored in a bunded / contained area.
Handling Hazardous Waste

24. Transportation
Hazardous waste shall be securely packed and labelled to ensure the waste
can be transported safely to the approved disposal site without risk to those
handling the waste or to the environment
Hazardous waste shall only be loaded within a hazardous waste storage
area or unloaded at the final waste disposal location.
Contractors shall maintain documented records of disposal methods.
The SM shall ensure that the waste hauling and disposal Contractor
maintains accurate records and Waste Logs for all hazardous wastes
transported from the Project site.
All containers must be appropriately labelled. All labels should be in
English, Arabic and pictograms.
