Cards can be used as mini Safety Data Sheets (SDS) using the criteria in NFPA 704 “Standard System for the Identification of the Hazards of Materials for Emergency Response“,

Images and Environmental impact scores are derived from the UN GHS “Globally Harmonized System of Classification and Labeling of Chemicals“

Explosive

Flammable

Oxidizing

Compressed Gas

Corrosive

Toxic

Irritant

Health Hazard

Environmental Hazard
These cards can be used to play Top Trumps (although it is preferential to have cards with the lowest scores to minimise the hazard potential rather than the conventional highest score wins).
Safety Impact
NFPA 704 scores are summarised as follows:
VALUE
HEALTH
FLAMMABILITY
INSTABILITY
4
Under emergency conditions can be Lethal
Rapidly or completely vaporize at atmospheric pressure and normal ambient temperature or that are readily dispersed in air and burn readily
In themselves are readily capable of detonation or explosive decomposition or explosive reaction at normal temperatures and pressures
3
Under emergency conditions can cause Serious or Permanent Injury
Liquids and solids (including finely divided suspended solids) that can be ignited under almost all ambient temperature conditions
In themselves are capable of detonation or explosive decomposition or explosive reaction but that require a strong initiating source or must be heated under confinement before initiation
2
Under emergency conditions can cause Temporary Incapacitation or Residual Injury
Must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur
Readily undergo violent chemical change at elevated temperatures and pressures
1
Under emergency conditions can cause Significant Irritation
Must be preheated (under all ambient temperature conditions) before ignition can occur
In themselves are normally stable but that can become unstable at elevated temperatures and pressures
0
Under emergency conditions would offer no hazard beyond that of ordinary combustible materials
Will not burn under typical fire conditions, including intrinsically non-combustible material
In themselves are normally stable, even under fire conditions
Special Hazards are indicated as follows:
W
Reacts violently or explosively with water
OX
Possess oxidising properties
SA
Simple asphyxiant including Nitrogen, Helium, Neon, Argon, Krypton & Xenon as well as liquefied carbon dioxide (Dry Ice)
BIO ☣
Biological Hazard
RAD ☢
Radiological Hazard
Environmental Impact
Environmental Damage is summarised as follows based on Acute impact on aquatic receptors:
Code
H400
H401
H402
H410
H411
H412
H413
Hazard Statement
Very toxic to aquatic life (acute)
Toxic to aquatic life (acute)
Harmful to aquatic life (acute)
Very toxic to aquatic life with long lasting effects
Toxic to aquatic life with long lasting effects
Harmful to aquatic life with long lasting effects
May cause long lasting harmful effects to aquatic life

We recognise that it’s impractical to develop a set that covers all chemicals, therefore we welcome site, company or industry specific enquiries where we can develop an appropriate deck of relevant materials.
Quizzes
Cards can be used in a variety of ways e.g. blank cards with only the name of the chemical could form the basis of a quiz to gauge participants knowledge of materials handled – for example identify/estimate the scores or rank them in order.

A sample Chemical Safety quiz is available via this icon:
Emergency Response
Mini Safety Data Sheets could be used by First Responders to prepare them for the potential hazards they may encounter when entering or isolating a release site.
