Aerosol spray products are widely used across industries, from cosmetics and household cleaners to automotive chemicals.
To ensure consumer safety and regulatory compliance, aerosol spray packaging must meet strict safety standards. These regulations protect both manufacturers and end-users by preventing accidents related to pressurization, leakage, or misuse.
Aerosol Can Safety Regulations
Compliance with aerosol safety regulations is mandatory in most markets. These rules are set by international and national authorities, such as the UN Recommendations on the Transport of Dangerous Goods, the U.S. Department of Transportation (DOT), and the ADR (European Agreement concerning the International Carriage of Dangerous Goods by Road).
The focus is to guarantee that aerosol containers remain safe under varying conditions, including transportation, storage, and consumer use. Manufacturers must provide accurate labeling, hazard symbols, and usage instructions to minimize risks.

1. Container Design and Integrity
Aerosol containers must be designed and constructed to withstand the internal pressure of the gas and product mixture, as well as external stresses.
- Pressure Resistance: Containers must be strong enough to hold the compressed, liquefied, or dissolved gas propellant. They are subjected to tests like the hot water bath test (or approved alternatives) where every filled container is checked for leaks and to ensure it can handle elevated temperatures and pressure before leaving the factory.
- Material and Capacity: Regulations often specify maximum capacity for different materials (e.g., metal, glass, plastic).
- Valve and Actuator: The self-closing release device must be properly assembled and functional to ensure safe and controlled dispensing.
Importance of Aerosol Cans
그만큼 에어로졸 캔 is not only a packaging medium but also a pressure vessel. Its design must withstand internal gas pressure while maintaining integrity during handling. Materials such as tinplate or aluminum are commonly used because they combine strength with corrosion resistance. The shape and sealing technology also play a critical role in ensuring safety.
2. Chemical Composition and Flammability
- Flammability Classification: Aerosols are classified by their flammability (e.g., Level 1, 2, or 3 aerosols in fire codes) based on the contents and test results like flame projection and flashback.
- Propellant Safety: The selection and concentration of propellants (like hydrocarbons) must adhere to safety limits. Certain hazardous propellants, like high amounts of HFC-152a and HFC-134a in duster products, are sometimes banned or have restrictions imposed by agencies like the U.S. Consumer Product Safety Commission (CPSC) due to intentional inhalation abuse hazards.
- Environmental Regulations: The use of chemical substances is also governed by environmental regulations, such as the EU’s REACH regulation, which can impact propellant choice.
Pressure Testing Requirements
One of the most critical steps in aerosol packaging safety is pressure testing. Cans must be tested at pressures significantly higher than normal operating levels to verify durability. Standard tests include water bath testing, burst pressure checks, and leak detection. Only those containers that meet or exceed safety thresholds are approved for commercial use.
3. Labeling and Warnings ⚠️
Labeling is a crucial tool for consumer safety, providing clear instructions and warnings. Regulations specify the content and placement of cautionary statements.
- Hazard Statements: Labels must clearly state potential hazards, such as flammability (e.g., “Extremely Flammable”), irritancy, corrosiveness, or the ability to generate pressure.
- Precautionary Measures: Warnings must include instructions like:
- “Keep out of reach of children.”
- “Do not puncture or incinerate.”
- “Do not expose to heat or store at temperatures above [specified temperature].”
- “Use only in a well-ventilated area.”
- Net Quantity: The packaging must disclose the net quantity of the commodity (including propellant) that will be expelled when the directions are followed.
- Regulatory Basis: In the U.S., the Federal Hazardous Substances Act (FHSA), enforced by the CPSC, mandates these precautionary labeling requirements. In the EU, the Aerosol Dispensers Directive (ADD) and the CLP Regulation govern labeling.
Safety standards for aerosol spray packaging are comprehensive, covering design, manufacture, testing, labeling, and transportation to mitigate risks associated with their pressurized, and often flammable or hazardous, contents.
The specific regulations vary by region and regulatory body. Key safety requirements generally address the following areas:
4. Transportation and Storage
Due to the pressurized nature and often flammable contents, aerosols are classified as dangerous goods for transport.
- UN Codes: For international and domestic shipment, aerosol packaging must be labeled with appropriate UN codes (like UN 1950) and symbols indicating the contents are pressurized and/or hazardous.
- 포장: Outer packaging must be sturdy, impact-resistant, and lined to prevent cans from shifting and building pressure or sustaining damage.
- Transport Orientation: Cans are typically required to be transported vertically to minimize leak and rupture risk.
- 저장: Specific fire and building codes (often citing standards like NFPA 30B or local ordinances) govern maximum quantities, segregation from other flammables, and necessary fire suppression or caged enclosures for storage in manufacturing and retail facilities.
