Dangers of Gases and Vapours: Risks and Protection
Understanding Gas and Vapour Hazards
Gases and vapours pose significant dangers, often invisible to the naked eye. Not only are they potentially harmful, but they can also be flammable or explosive. Despite lacking a distinct smell, when mixed, they can amplify the danger.
Sources of Gases and Vapours
Gases can originate from various sources, including leaking pressurised gas cylinders, gas pipes, or emissions from sewage pits. Vapour, on the other hand, emanates from substances and can immediately impact health.
Visibility and Detection
While gases and vapours may not always be visible, some signs such as a slight shimmer in the air around a chemical may offer a warning. However, this is not consistent. Additionally, gases and vapours, being sometimes heavier than air, can accumulate in lower areas like pits or buildings.
Protective Measures
To safeguard against gas and vapour hazards:
- Avoid areas where gases or vapours may be present.
- Always wear appropriate personal protective equipment (PPE) when risks are known.
- Utilise gas detection alarms to alert you to the presence of hazardous substances.
In certain work environments, gas detection alarms are mandatory and can be portable or permanently installed throughout the site.
