    <ul className="space-y-2">
    <li>
    <strong>Safe</strong> – Materials marked as safe are widely considered to be generally safe by the laser
    community at large. This does not mean normal safety protocols should not be observed.
    </li>
    <li>
    <strong>Level I – Caution</strong> | These materials are typically safe when normal safety protocol
    observed. This includes skin, eye and respiratory protection, regulated marking parameters, and proper
    exhaust and filtration.
    </li>
    <li>
    <strong>Level II – Dangerous</strong> | These materials can be harmful even if normal safety protocol
    observed. Strict adherence to safety protocols required at all times. Exercise extreme caution and
    mindfulness.
    </li>
    <li>
    <strong>Level III – Critical Hazard</strong> | These materials pose an imminent threat of bodily harm or
    death. Materials marked Critical Hazard should not be processed by lasers in any environment for any
    reason.
