Can Cooking Gas Cylinders Be Left in the Sun? What LPG Users Should Know

It is easy to see a gas cylinder outside and think, “It is only a little sun.” In Nigeria, hot weather makes this worth thinking about.

LPG is stored under pressure. So, where you keep the cylinder matters. You do not need to panic about normal outdoor temperatures. However, avoid unnecessary heat and direct sunlight when choosing a storage position.

Can a gas cylinder be left in direct sunlight?

A cooking gas cylinder should not sit in strong, direct sunlight for long periods.

As the cylinder heats up, the LPG inside can become more pressurised. Therefore, good storage keeps cylinders away from direct sunlight and other heat sources.

This does not mean a few minutes in the sun is an immediate emergency. The goal is to avoid making direct heat exposure a normal storage habit.

Why does heat matter to LPG?

LPG inside a cylinder exists mainly as liquid, with vapour above it. When the cylinder gets hotter, the pressure inside can rise.

The cylinder is designed to contain LPG safely when used and stored correctly. For that reason, keeping it away from unnecessary heat is sensible.

Heat becomes a bigger concern near flames, hot equipment, engine exhausts or other strong heat sources.

Where should you keep a cooking gas cylinder?

For a typical household cylinder, choose a suitable outdoor or well-ventilated location.

Also protect the cylinder from direct sunlight and excessive heat. Keep it upright on a stable surface.

Do not place it where it can easily fall or be struck by a vehicle. Keep rubbish and other combustible materials away from it.

Good airflow also matters. LPG vapour is heavier than air. If there is a leak, vapour can collect in low or poorly ventilated areas.

So, when choosing between two locations, look for shade, ventilation and stability. The cylinder should also have protection from accidental damage.

What about keeping the cylinder under a roof?

A roof or suitable shade can help protect a cylinder from direct sunlight. However, shade should not mean enclosing the cylinder.

Avoid placing it inside a sealed cupboard or enclosed room. Leaked LPG could collect in such a space.

Instead, choose a setup that protects the cylinder from heat while allowing good airflow.

What if your cylinder has been sitting in the sun?

If you notice direct sunlight on your cylinder, do not pour water over it. Do not try to cool it suddenly.

If it is safe, remove the heat source and move the cylinder to a shaded, ventilated location. Do this without dropping, dragging or damaging it.

If natural shade is unavailable, you can use a simple overhead shade. This can help block direct sunlight from reaching the cylinder.

Make sure the shade does not touch or enclose the cylinder. It should not restrict ventilation.

If the cylinder is extremely hot, damaged or leaking, do not handle it yourself. The same applies if it is involved in a fire.

Move people away from danger and seek help from the appropriate emergency or LPG professional.

Sunlight is not the only thing to watch

It is easy to focus on the weather and forget what is around the cylinder.

Keep the cylinder away from open flames, generators and hot engines. Also keep it away from other strong heat sources.

Do not allow rubbish, fuel or other easily ignited materials to build up around it.

Also check the cylinder itself. A damaged cylinder needs attention, regardless of where you store it.

The same applies to a leaking valve or faulty connection. These issues need attention before normal use continues.

Frequently asked questions

Can I keep my gas cylinder outside?

Yes, a suitable outdoor location can be appropriate. Keep the cylinder upright, stable and well ventilated.

Also protect it from direct sunlight and excessive heat. Keep it away from other hazards.

Can a gas cylinder explode because of sunlight?

Sunlight alone does not mean a cylinder will explode. However, heat can increase pressure inside the cylinder.

Therefore, avoid unnecessary direct heat exposure. Follow safe storage practices as well.

Should I cover my gas cylinder?

A suitable shade can protect the cylinder from direct sunlight. However, do not cover or enclose it in a way that blocks ventilation.

What should I do if my cylinder becomes very hot?

Keep people away from danger. Remove the heat source only if it is safe.

Do not handle a cylinder that is severely overheated, damaged or leaking. Instead, seek professional or emergency assistance.

A little shade is a sensible safety habit

You do not need to treat every sunny day as a gas emergency. Still, there is no reason to leave an LPG cylinder in direct sunlight when shade is available.

Keep the cylinder upright, stable and well ventilated. Also keep it away from unnecessary heat.

These simple choices can make everyday cooking-gas use safer. At JP GasPoint, we believe safe LPG use starts with small habits.
