Under pressure. . . .the trouble with Gas Cylinders

How often are you checking your gas cylinders condition?

Gas cylinders generally contain compressed gas, stored under significant pressure. There are a variety of gas cylinders that pose a potential hazard due to their chemical properties. This can include, but is not limited to, flammable gases, toxic or corrosive gases, oxidising gases (spontaneous combustion) and asphyxiation from displacement of oxygen. Therefore it is imperative that gas cylinders are frequently checked for hazards that could create catastrophic affects.

What can you do?
To prevent the risk of any hazards, the best undertaking is to mitigate any associated risks.

As a result it is generally recommended that:
– Cylinders are stored in a well ventilated outdoor area
– Ensure nothing is stored on top of the cylinders
– Regularly check that cylinders are within their use by dates
– Complete routine maintenance checks on cylinders; namely O-rings, valves and the general condition of the cylinder.
– Keep away from ignition sources (i.e. timber, paper, dried leaves, etc.)
– Keep minimal volumes

Toxfree is capable and licensed to collect and dispose of gas cylinders in a safe manner. Gas cylinders are generally collected in cages to suit the cylinders and segregated from potential dangerous goods that may react with it. Moreover, Toxfree’s Laverton facility is home to the Plascon Unit which destroys Ozone Depleting Substances (ODS).

Toxfree Thermal Desorption

As a waste generator or holder, you are responsible to know what your waste is and to ensure that it ends up at a lawful waste facility. This is irrespective of whether your waste is disposed, treated, recycled or applied to land. One stream of waste that Toxfree can help with is Dieldrin, often found in soils.SoilTest1

Dieldrin is a chlorinated hydrocarbon originally produced in 1948 by J. Hyman & Co, Denver, as an insecticide. Dieldrin is closely related to aldrin, which reacts further to form dieldrin. Aldrin is not toxic to insects; it is oxidized in the insect to form dieldrin which is the active compound. Both dieldrin and aldrin are named after the Diels-Alder reaction which is used to form aldrin from a mixture of norbornadiene and hexachlorocyclopentadiene.

Originally developed in the 1940s as an alternative to DDT, dieldrin proved to be a highly effective insecticide and was very widely used during the 1950s to early 1970s. Endrin is a stereoisomer of dieldrin. Dieldrin often ends up in soil after application.

However, it is an extremely persistent organic pollutant; it does not easily break down. Furthermore it tends to biomagnify as it is passed along the food chain. Long-term exposure has proven toxic to humans and a very wide range of animals, far greater than to the original insect targets. For this reason it is now banned in most of the world.
It has been linked to health problems such as Parkinson’s, breast cancer, and immune, reproductive, and nervous system damage. It can also adversely affect testicular descent in the fetus if a pregnant woman is exposed to it.

As a waste generator or holder, you are responsible to know what your waste is and to ensure that it ends up at a lawful waste facility. This is irrespective of whether your waste is disposed, treated, recycled or applied to land.

Thermal Desorption is a “physical separation process” where heat is used to desorb (evaporate moisture and contaminants from solids). Evaporated contaminants are either converted (generally to Carbon Dioxide and Water) or condensed and collected. The temperature in the Thermal Desorber vessel is increased above the boiling point of the organic compound to be removed. Samples of the treated waste are analysed to verify complete decontamination prior to reuse, recycling or disposal. Soil is typically treated at temperatures up to 550°C and retains its physical properties after treatment so that it can be beneficially reused.
Toxfree operates two types of thermal desorption;
• Direct Heated Thermal Desorption (DTD) – a continuous single shell rotary dryer process with a converter unit for bulk soil treatment at rates of up to 50 tonnes per day.
• In-direct Heated Thermal Desorption (ITD) – a dual shell process with a condensation unit for smaller soil volumes and specialist removal of organic contaminants from solid material i.e. PCB Capacitors and Solid Pesticides.
