Proposition 65 Compliance Assessment for 48 Tools Products

This document provides a detailed Proposition 65 compliance assessment for 48 Tools products made from ABS plastic. Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, requires businesses to inform Californians about significant exposures to chemicals that may cause cancer, birth defects, or other reproductive harm. The assessment evaluates exposure to Proposition 65-listed chemicals present in trace amounts within the ABS material under typical product usage scenarios.

Findings

1. Acrylonitrile

Acrylonitrile is listed under Proposition 65 as a chemical known to cause cancer. The Safe Harbor Level, specifically the No Significant Risk Level (NSRL), for acrylonitrile is 0.7 µg/day. The ABS plastic used in 48 Tools products contains a maximum of <100 ppm acrylonitrile. For a 184-gram product, this equates to a total of 18.4 µg of acrylonitrile. Considering a conservative migration rate of 0.0001% per day reflecting the wall-mounted and minimal-contact nature of the product, the estimated daily exposure is 0.0184 µg/day. This exposure level is significantly below the NSRL, indicating compliance with Proposition 65 for this chemical.

2. 1,3-Butadiene

1,3-Butadiene is listed under Proposition 65 for both cancer and reproductive toxicity. The Safe Harbor Levels are as follows:
• NSRL for cancer: 0.4 µg/day
• Maximum Allowable Dose Level (MADL) for reproductive toxicity: 55 µg/day
The ABS material contains a maximum of <50 ppm 1,3-butadiene, which corresponds to 9.2 µg in a 184-gram product. Assuming the same conservative migration rate of 0.0001% per day, the estimated daily exposure is 0.0092 µg/day. This value is well below both the NSRL and MADL, confirming compliance with Proposition 65 for 1,3-butadiene.

3. Styrene

Styrene is listed under Proposition 65 as a chemical known to cause cancer. The NSRL for styrene is 27 µg/day. The ABS material contains a maximum of <1600 ppm styrene, equivalent to 294.4 µg in a 184-gram product. With a migration rate of 0.0001% per day, the estimated daily exposure is 0.2944 µg/day. This value is significantly below the NSRL for styrene, indicating compliance with Proposition 65 for this chemical.

Compliance Summary

Based on the calculated exposure levels and comparison to Proposition 65 Safe Harbor Levels, 48 Tools products made from ABS plastic comply with Proposition 65 for the evaluated chemicals under typical usage scenarios. Key points include:
• All evaluated chemicals (acrylonitrile, 1,3-butadiene, and styrene) have estimated exposure levels below their respective Safe Harbor Levels.
• The products are wall-mounted, with minimal user interaction, further reducing potential exposure risks.
• The conservative assumptions used in this assessment ensure a robust evaluation of compliance.

Notes for Website Presentation

48 Tools takes safety and regulatory compliance seriously. Our products are designed and manufactured to meet stringent safety standards, including compliance with California Proposition 65. The following are key compliance statements:
1. Our ABS plastic products have been evaluated for chemicals listed under Proposition 65, including acrylonitrile, 1,3-butadiene, and styrene.
2. Estimated exposure levels for these chemicals are significantly below Safe Harbor Levels under typical usage scenarios.
3. The wall-mounted design of our products ensures minimal user interaction, further reducing exposure risks.
