The symbol for serious health hazards is a human head and shouders with a star-shaped internal health hazard symbol. It can include “Respiratory sensitiser, mutagen, carcinogen, reproductive toxicity, systemic target organ toxicity, aspiration hazard” – things that can cause long term, very serious damage to your health.

Now, as the world begins to reduce the restrictions in place and return to some sense of normality during the ongoing COVID-19 pandemic, daily social interactions will increase. However, also during this time, everyone should be careful about maintaining a physical distance to avoid a second wave of COVID-19 infections—yet at the same time remain social, supportive, and empathetic toward one another. Let us be inclusive, in both our words and our actions, so that no one feels excluded or isolated from their wider community.

Workplace Exposure Limits (abbreviated to WELS) are limits set on the amount of exposure limits applied to certain hazardous substances under COSHH. This can be from breathing in, coming into contact with skin or eyes, through puncturing the skin or by swallowing. They exist to protect people both in the short and long term to protect people’s health. This is usually displayed with the details of the product and covered as part of the Material Safety Data Sheet (MSDS).

Hazard symbol

We hope you found this guide to hazard symbols useful. As we said above, it is useful to familiarise yourself with these hazard symbols, even if it is not something you use in your work, you could have a situation where you come into contact with these signs so be alert and take care when you see them.

The symbol for an explosive hazard is an image of an exploding bomb and refers to reactive substances that could explode when dry or through exposure to heat or a flame, possibly causing property or severe injury to a person.

The symbol for a flammable hazard is an image of a flame to signify items that may catch fire in contact with air or an ignition source or other flame. It includes “Flammable gasses, flammable liquids, flammable solids, flammable aerosols, organic peroxides, self-reactive, pyrophoric, self-heating, contact with water emits flammable gas”. Such solutions are advised to be kept stored in fire-resistance storage cabinets.

We will now look at each of the 9 hazard symbols and meanings one by one, in each of the cases below we show the symbol on the left with the name of it to the right. However, in most instances the logo will not have that description shown the same so it is very useful to know them from sight. We discuss hazard symbols in our guide to fluorescein.

There are 9 main hazard warning symbols that are all red diamond borders with white backgrounds and black symbols on them to indicate which warning it is portraying. They show symbols for explosives, flammable materials, acute toxicity, oxidising, corrosive, hazardous to the environment, gas under pressure, health hazards and serious health hazard symbols, each with a different meaning.

The main hazard symbols can be seen in the image below, in the 3 x 3 grid on the left and we will explain them, and some other interesting and relevant safety symbols in this article (such as the two in the bottom right corner). Some of these hazard symbols are relevant to things like mould removal services and treatments, which we are experts in, especially mould in homes and businesses locally.

Hazardsymbols and meanings

After one of the authors who is also the Chair of the EPA Ethics Committee (D.W.) alerted the WHO Mental Health and Substance Abuse division that the term “social distancing” was adversely influencing vulnerable groups, the WHO’s COVID-19 response team on March 23 addressedthe media stating that the term “physical distancing” will replace “social distancing” for the sake of mentally ill persons.

Policy makers, media, governments, and the general public should be encouraged to use the more neutral term of “physical distancing” rather than “social distancing” during the COVID-19 pandemic on the basis of the negative connotations of this term.

The symbol above is used to indicate a biohazard or biological hazard and can cover a number of things which can pose a threat to living organisms, including human life. This can include viruses (such as Covid-19 / Coronavirus) or toxins. There are a number of categorisations and levels of this which can be seen and explained in more detail on the Biological Hazard Wikipedia page.

While the large majority of the general population are unlikely to react negatively to the term of social distancing, it is important that the majority is informed and aware of how vulnerable groups in society perceive and react to this term. The literacy of the general population about mental health is unfortunately still very low, as well as the knowledge about how it is possible for lay people to support persons with mental health problems [9].

Suicidal ideation is common among a broad group of patients with mental problems, including affective, psychotic and anxiety disorders. People with suicidal ideation have a pessimistic and dark outlook on life, and may be very sensitive to any signs of rejection. The suicidal process may be accelerated due to an interplay between the receivers’ desperate and chaotic feelings and the communication that “social distancing is necessary” circulating throughout every level of society. The inner psychological entrapment of persons close to suicide [4] can be magnified not only by physical entrapment in the lockdown situations, but also by the terminology used of social distancing. In individuals at risk of psychotic breakdowns, the appearance of face masks and goggles is likely to induce distrust easily shifting into paranoia. Negative emotions, evoked by social distancing connotations, are unfortunately all too real for the beholder and have a crucial bearing on vulnerable persons, especially those who are prone to suicidal actions and ambivalent to living or dying [2]. During these unprecedented times, filled with anxiety about COVID-19 consequences, emotional closeness, connection, and inclusivity are increasingly important [5].

Corrosivesymbol

The symbol for gases under pressure shows a gas cylinder (or bottle) and can include gases, liquified gases etc. The risk from these not only comes (potentially) from the contents but moreover the fact that they are pressurised. In fact, in some instances the gas could be inert. We have more on this later.

Hazard warning symbols are present to indicate substances, in particular chemicals that present a risk, including to harm human health. There are 9 main symbols on the GB CLP (Classification, Labelling and Packaging) pictograms in the shape of a diamond with a red border and black symbols on a white background. They replace older (orange) symbols in the UK which have been phased out so as to be consistent with global standards for hazard symbols.

In times of crisis, there are centrifugal movements among the general public. On one side, we see solidarity and more care for each other; on the other side, sadly prejudice reigns. The term social distancing may enhance latent racism or xenophobia, especially against migrant groups and refugees [6]. It may also increase the isolation of children and women, who are prone to domestic violence [7]. In all these groups, the term social distancing, as well as the fact that they are closely locked-down with their potential aggressors with reduced opportunity for being helped by others, is strongly pathogenic. Moreover, in many vulnerable groups and in frail elderly, the lockdown may induce or enhance loneliness and feelings of being a burden to their dear ones and society in general. This can lead to feelings of depression and eventually suicidal thoughts and acts [8].

Importantly, COSHH does not cover lead, radioactive substances or asbestos. For more information about asbestos, see our asbestos testing and removal page and our recent article about artex and possible asbestos.

Healthhazard symbol

The meaning of a hazard is something with the potential to cause harm, injury or illness. In extreme situations a hazard can have the potential to cause death. This is why understanding hazard meanings, such as those on chemicals, can be critical to good health and safety practices. In identifying and understanding hazards, as part of a risk assessment, you can help to mitigate the associated risks (for example with PPE).

Toxicsymbol

On the subject of flammable materials, we have an article about fire classification and a similar useful guide, with explanatory diagrams about the fire triangle components.

Different items covered by COSSH will likely have WELS (Workplace Exposure Limits) more on this later. In the meantime, we have another interesting article about Christmas Fire Safety Tips which includes electrical fires.

You may often see hazard symbols with precautionary statements alongside them to help mitigate the risk from the relevant hazards, examples could include:

The symbol for chemicals that are hazardous to the environment shows a tree and (apparently) dead fish. These substances can cause immediate or longer term damage to the environment (plants and animals – including fish) including having toxic effects on aquatic life. Amongst other things, safe disposal is key for these.

These red and black symbols replaced older symbols (known as CHIP symbols – Chemicals Hazard Information and Packaging for supply) that were orange and black, which have been phased out, like the ones shown below:

The corrosive hazard symbol is a picture of two test tubes spilling or pouring over a material or flesh (shown as a hand) and indicates things that can cause serious skin damage (including burns) and eye damage if it comes into contact with them. This is another one where appropriate PPE can help and, in the case of accidental exposure, the correct first aid / medical support is very much relevant. This can include things like strong acids or alkalines.

The 9 hazard symbols and their meaning are – an exploding bomb (for explosives), a flame (flammable materials), skull and crossbones (acute toxicity), a circle with flames on top (oxidising), test tubes dripping on a substance and hand (corrosive), a dead tree and fish (hazardous to the environment), gas cylinder (gas under pressure), exclamation mark (health hazards) and a head and shoulders image with a star-like internal damage symbol (indicating serious health hazard symbols)

Hazard symbols and their meanings provide useful information in a visual image form, to alert people of the presence of a hazardous chemical that could harm people or the environment. Most of the images in this guide cover what is known as the GB CLP Regulation, linked to the European Regulation (EC) No 1272/2008.

This is not one of the red and white CLP Hazard Symbols but it is something you might see. There are different variants but this one above is for ‘Class 2‘ which has sub-classes of non-flammable or non-poisonous compressed gas. In our case, we sometimes use tracer gas for our water leak detection service. Tracer Gas is generally 5% Hydrogen and 95% Nitrogen.

These CHIP symbols were replaced in June 2015 – see the HSE website for more details. As you can see, there are some similarities with the newer versions which are aligned to global standards for consistency across the world.

As COVID-19 has plagued our world, the term “social distancing” has been widely used with the aim to encourage the general population to physically distance themselves from others in order to reduce the spread of the virus. However, this term can have unintended but detrimental effects, as it evokes negative feelings of being ignored, unwelcome, left alone with one's own fears, and even excluded from society. These feelings may be stronger in people with mental illnesses and in socio-economically disadvantaged groups, such as stigmatized minorities, migrants, and homeless persons [1], many of them also having high risk for suicidal behaviors [2]. Mental health disorders are pervasive worldwide; the global burden accounting for approximately 21.2–32.4% of years lived with disability—more than any other group of illnesses [3]. So, the vulnerable group of people with mental health disorders represents a considerable share of the total global population.

The HSE page also mentions the related subject of COSHH which is the Control of Substances Hazardous to Health Regulations, which can include chemicals as well as products containing chemicals, fumes, dusts, vapours, mists, nanotechnology, gases, asphyxiating gases and biological agents (germs) – including those that can cause diseases. Exposure risks to these could be via – skin contact (or puncturing the skin), contact with eyes, swallowing and breathing in.

As psychiatrists, along with other mental health professionals, we must embrace, alongside our daily tasks of early detection, treatment, and rehabilitation of persons with mental disorders, the job of increasing public mental health awareness and collaborating with public health institutions by giving information, advice, and guidelines [10]. We should draw to their attention the benefits of phone contact, the options for basic psychological support, and the availability of stepped care whether online support, an app or remote support, and/or treatment from a community service [11].

The notion of “social distancing” affords neither comfort nor help to vulnerable people. They are often reliant on social connection and relations, so a sudden break in those, perceived or real, has devastating consequences. Therefore, we advocate to use the term “physical distancing”—as a physical distance of 2 m will prevent and diminish the spread of COVID-19—rather than the term “social distancing” [1].

The symbol for oxidising hazards is a circle with a flame on top of it and is for substances that can react with other substances / materials that may cause explosive damage, heat, fire or even damage to living tissues.

These regulations are also related and linked to the United Nations ‘Globally Harmonised System’ (GSH) for the Classification, Labelling and Packaging (CLP) of chemical substances. For more please see the useful HSE CLP guide and for more detail.

The symbol for acute toxicity is a skull and crossbones which indicates a substance that can cause serious health risks or, possibly even death if it is ingested, inhaled or if it penetrates your skin. This is an example of something that, with the correct corresponding PPE (Personal Protective Equipment) can help mitigate the risk.

It is also worth mentioning that, when these logos appear on cleaning chemical labels for example, like those we use as part of our specialist cleaning services, it will likely have additional information than just the logo so do check that and also the relevant safety data sheets (SDS) plus instructions for that product.

The symbol for health hazards is an exclamation mark, showing things that can cause harmful skin irritation, dangerous / serious eye irritation, harm to the ozone layer and even acute toxicity. This can be from biohazards too, which we will discuss further later as there is a symbol people often associate with that too.
