Chemical

Inherently, petrochemical plants are home to a host of hazardous, combustible gases which present significant risks during production. It is paramount that all plant practices, warnings, and emergency procedures are observed at all times.

Chemical Storage

Maintaining the integrity of storage facilities is paramount. Early warning of any leak improves the safety of the facility and those living or working around it. When detected at an early stage, countermeasures can be initiated to protect personnel, workplaces and equipment. Gas detection systems are installed to focus on flanges and any potential weak points where leaks may occur. These systems can give local alerts as well as taking executive action to adapt gas flow and storage rates.  

Maintenance

Any maintenance works carried out which involve welding, soldering, cutting and brazing should be covered under a Hot Work permit, and require the use of area and personal detectors to maintain a safe working atmosphere. In this environment, you need a reliable warning and protection system. Respiratory protective filters can also be worn under welding masks to protect against nuisance odours and particulates. 

Confined Space

At any point, a large and complex amount of gases, which lead to atmospheric contamination hazards, will be present. With gases such as Nitrogen and Sulphur present at any time, workers are exposed to the risks of explosion, corrosiveness and asphyxiation. Combined and in a potential enclosed space, these gases pose much more of a threat than they would individually.

Common gas hazards include:

  1. Ammonia (NH3)
  2. Carbon Dioxide (CO2)
  3. Carbon Monoxide (CO)
  4. Chlorine (Cl2)
  5. Combustible Gases
  6. Hydrogen (H2)
  7. Hydrogen Chloride (HCl)
  8. Hydrogen Sulphide (H2S)
  9. O2 (Enrichment/Deficient)
  10. Sulphur Dioxide (SO2)
  11. Volatile Organic Compounds (VOC).

Chemical plants manufacture a vast number of products and feedstocks. The diversity of chemicals used on site during manufacturing processes provides danger to plant and personnel in the form of toxic and flammable gases.
