Which statement about the availability of CAMEO Chemicals and CRW is true?

• A. CAMEO Chemicals is free
• B. CRW is free
• C. Both are free
• D. Neither is free

Answer: (C)

Both CAMEO Chemicals and CRW are freely accessible resources for hazard and reactivity information, which is why the statement that both are free is true. CAMEO Chemicals is an online database you can visit to look up chemical hazards, incompatibilities, and recommended safety measures without paying a fee, making it a handy reference during storage planning, incident response, and training. The CRW (Chemical Reactivity Worksheet) is provided as a free tool within SAChE materials and similar safety education resources, offering a structured, quick-check approach to assessing potential reactive hazards for common chemical scenarios. Because you can use each tool without a paid subscription for the core data and guidance they provide, the correct choice reflects their shared availability.
