Frequently Asked Questions

Q. Where are acid signs required?

Acid signs are required in chemical storage rooms, laboratories, and near industrial tanks. They are especially critical in battery charging area signs due to the presence of sulfuric acid.

Q. What are acid warning signs?

Acid warning signs alert workers to the presence of corrosive acids. They use headers from our osha danger signs or "corrosive" labels and often include instructions for specific PPE. View the full range in our acid warning signs category.

Q. What symbol indicates acid?

The GHS symbol for acid/corrosive is a pictogram showing two test tubes dripping liquid onto a hand and a metal bar, causing damage to both. This is a standard feature on our corrosive signs.

Q. What is an "Acid Wear Required" sign?

This sign mandates the use of acid-resistant PPE, reminding workers to don aprons, gloves, and goggles. These are a specialized type of custom ppe signs and are often paired with eye protection signs.

Q. Are acid signs chemical resistant?

Yes, high-quality acid warning signs are made of materials like aluminum with a protective laminate that resists chemical fumes and splashes. This durability is comparable to our uv safety signs.

About our Acid Warning Signs

Shield workers, laboratory personnel, and emergency responders from the severe risks of acid exposure with acid warning signs that provide immediate, unmistakable hazard communication wherever corrosive substances are stored, handled, or used. Acids can cause serious chemical burns, respiratory damage, and long term health complications upon contact or exposure, making clear and visible warning signage an absolute necessity in any facility that works with corrosive materials. Our acid warning signs are designed to meet strict regulatory requirements while ensuring that everyone in or near acid handling areas is fully aware of the dangers and required protective measures.

• Acid warning signs are compliant with OSHA HazCom, ANSI Z535, and GHS standards, ensuring your facility meets all required corrosive material hazard communication and chemical safety regulations.
• Available in a comprehensive range of designs covering acid storage areas, corrosive material warnings, PPE requirement notices, and emergency response instructions to address every critical aspect of acid safety.
• Constructed from durable materials including aluminum, vinyl, and rigid plastic that resist chemical exposure and hold up reliably in laboratories, chemical plants, industrial facilities, and processing environments.
• Bold colors, high contrast text, and globally recognized GHS corrosive hazard symbols ensure acid warnings are immediately visible and clearly understood by workers, contractors, and emergency personnel alike.
• Suitable for use in research laboratories, pharmaceutical facilities, metal processing plants, battery storage rooms, and any location where acids or corrosive chemicals are stored, handled, or used on a regular basis.
