Know Your Pictograms

Understand Your CLP Requirements

Hazardous Substances and me, Should I be worried?– There are many hazardous substances out there which can affect us all in different ways, it’s natural to feel worried when we see pictograms on the products we buy and use.

Many of these classified substances are formulated into products that we use in our everyday lives and we can’t avoid them all, nor should we. The hazard labelling on products are designed to inform us about the Health and Safety risks, familiarising ourselves with the hazards and what risks they pose is important.

When thinking about packing your own products it is important that they comply with the CLP Classifications required for the materials you are using. Why not contact Grotech Production and let us take care of your product? – from formulating the best chemicals to selecting the correct packaging!

Explosive – depending on the hazard category substances may be seen as an explosion hazard. Examples of such could be cellulose nitrate which can violently decompose and/or combust under the right circumstances, such as with an ignition source.

Grotech Production don’t handle this type of material

Carcinogenic – Designed to signify threats to long term health, carcinogens (substances that cause cancer), mutagens (generic defects), reprotoxins (affecting fertility or harm to the unborn child).

An example of which could be Benzene, used as an additive in petrol, Methanol is an example of a STOT substance, known to cause damage to the optic nerve after a single acute exposure. GHS08

Irritant – This symbol can be difficult to interpret without additional context and hazard information. Lower category corrosive substances would apply to this pictogram for materials classed as irritants.

This pictogram can be seen on everyday items such as washing up liquid or laundry powders. It can also apply to skin sensitisers like fragrance oils which can cause skin irritation and trigger rashes and other allergic symptoms. GHS07

Compressed Gas – This pictogram doesn’t necessarily relate to the properties rather the storage conditions. Gases held under high pressure, such as propane (gas for your BBQ), liquefied gas (nitrogen) or refrigerated liquefied gas (such as carbon dioxide).

These may be subject to explosion where heated or can rapidly cool. GHS04

Environmentally Hazardous – As with all other pictograms this symbol can be applied to different types of categories, substances that carry this type of classification are wide ranging from organic solvents such as white spirits, salts used in fertilisers to pesticidal, herbicidal and biocidal materials.

As an agrochemical toll manufacturer these types of materials are the most frequently handled here at Grotech Production. GHS09

Flammable – Multiple types of flammable materials from desensitised explosives to flammable gases, liquids and solids.

Care must be taken when trying to interpret what is actually being communicated – Butane used in aerosol cans such as spray deodorants is an example of extremely flammable gas. GHS02

Corrosive – Corrosion to metals, skin and eyes. They are commonly applied to strong acids and bases such as sulphuric acid and sodium hydroxide.

Various salts and surfactants can be classed as corrosive to the eyes with even a content as low as 1% in a mixture can results in corrosive effects. GHS05

Toxic Substances – Probably the one pictogram which most actively draws attention. Referring to toxic substances applying to 3 possible routes of entry: ingestion, skin or eye contact and inhalation.

An example of a toxic chemical is methanol which is used as an antifreeze in screen washes.GHS06

Oxidiser – As with flammable materials, oxidisers can be gases, liquids or solids. Most powerful oxidising agents can cause or intensify fires.

Calcium Hypochlorite is used as the chlorine source in swimming pools and is similar to domestic bleach, this chemical would carry this pictogram. GHS03

Hazards with no Pictogram?

Certain classifications don’t always trigger the need for pictograms, such as “combustible” rather than flammable, substances that are “harmful” rather than toxic to the environment and under the GHS system.

Such hazards mean that at a casual glance of the labelling it may not immediately tell you what the hazards of that material are! This is for good reason as having the same pictograms applying to much or having too many pictograms which can be confusing. It just goes toshowthatsometimesitisworthwhilereadingthesmallprint!
