Fiber glass itself is reef safe because it is just glass fibers, but the resin they use to seal it may not be.
Tiny pieces of plastic called microplastics (a distinction based on size alone) are found in the ocean. Ceaselessly broken down by the elements over time, larger pieces of plastic become smaller and smaller. Microplastics are small enough to be ingested by sea animals, including those that end up on our plates.
Polyethylene terephthalate, which is also known as PETE, is No. 1 and is commonly used in aquarium products. Additionally, categories 2-4, HDPE, PVC and LDPE respectively, have been deemed safe for aquarium use, given their resistance to corrosion.

Inhalation of fumes from curing resin can cause oral irritation. It is advisable to keep your cats out of your work area. And if the resin comes in contact with the skin, it may cause dermal irritation. The mixture of resin and hardener is toxic.

Polyurethane is a polymer joined by urethane links. These links are formed by reacting a di- or poly-isocyanate with a polyol. Polyurethane is unique in that it is not manufactured like many other plastics. Most polymers, such as polyethylene, are produced in the form of a powder and then molded into a desired form.
