What are the warning signs of corrosion?

Corrosive marks are generally drawn with test tubes dripping with liquid. The liquid dripped on the horizontal cuboid and hand, and both cuboid and hand were damaged. As shown in the figure below:

Corrosive signs use pictures to visually show that items are corrosive. Generally, the words "corrosive" and "beware of corrosion" are clearly written in Chinese and English, which plays a warning role.

Setting of warning signs for other occupational hazards in the workplace:

Set warning signs of "injecting interest to prevent dust" and instructions of "wearing dust mask" in workplaces where dust is generated.

In workplaces where occupational burns and corrosion may occur, warning signs of "Be careful of corrosion" and indication signs of "Wear protective clothing", "Wear protective gloves" and "Wear protective shoes" should be set.

In the workplace where noise is generated, warning signs of "noise is harmful" and indication signs of "wear ear protectors" should be set.

In high-temperature workplaces, set up "Pay attention to high temperature" warning signs.

In the workplace that may cause electro-optic ophthalmia, set up a warning sign of "beware of arc light" and an indication sign of "wear protective glasses".

In workplaces where biological occupational hazards exist, warning signs and corresponding indication signs of "beware of infection" should be set up.

In workplaces where radioactive isotopes exist and radioactive devices are used, warning signs and corresponding indication signs of "Caution against ionizing radiation" should be set up.
