When purchasing potentially hazardous products, it is important to ensure that the device meets both your practical requirements and all necessary safety requirements. With the proliferation of lasers as tools and toys of everyday life, it is easy to forget that they present risks to users and others.
The Food and Drug Administration recently issued a consumer alert – Illuminating Facts About Laser Pointers, 13 June 2019. When using laser pointers, be sure to follow all recommended safety protocols, including (quoting the document):
- Never aim or shine a laser pointer at anyone.
- Don’t buy laser pointers for your children.
- Before purchasing a laser pointer, make sure it has the following information on the label:
- a statement that it complies with Chapter 21 CFR (the Code of Federal Regulations)
- the manufacturer or distributor’s name and the date of manufacture
- a warning to avoid exposure to laser radiation
- the class designation, ranging from Class I to IIIa. Class IIIb and IV products should be used only by individuals with proper training and in applications where there is a legitimate need for these high-powered products.
