strand between high- and low-water marks); 2. beach debris (may
be natural beach debris - seaweed etc. - and/or marine debris
- which by definition is human-caused) / LAMMA

oxygen concentration (max. O2
concentration in a mixture of
a flammable substance and air and an inert gas in which an explosion
will not
occur, determined under specified test conditions)
/ LOD
=
limit of detection (smallest
amount of substance in a sample which
can be identified but not precisely quantified; cf. also LOQ)
/ LOI
= Limiting Oxygen Index (fire
resistance) / loopvloeistoff
