2. Tso cov foob pob hluav taws. Tom qab txiav txim qhov chaw nyob, theem tom ntej yog cais cov foob pob hluav taws raws li lawv lub zog. Ntawm lawv, cov hluav taws kub-hluavtaws hav zoov yog qhov muaj zog tshaj plaws. Ntawm lawv, lub qhov me me tshaj plaws muaj qhov taub ntawm 4 cm thiab qhov loj tshaj plaws lub qhov muaj qhov taub ntawm 6 cm (uas yog, peb feem ntau hais tias lub foob pob hluav taws kub muaj qhov siab li 50 metres thiab tib rab phom loj hnyav 50 phaus). Tso cov foob pob hluav taws hauv ntau qhov chaw, nrog qhov chaw ntawm 6 metres ntawm thaj chaw.

Qhov no yog ua kom sib npaug ntawm cov cua sov tso tawm thiab tiv thaiv kom tsis txhob muaj hluav taws xob kub sai sai uas tuaj yeem ua rau tawg qias neeg tawg.
3. Txoj kev ntawm kev rhuav tshem. Txhawm rau pab txhawb kev tiv thaiv kev tiv thaiv thiab kev tawm tsam tag nrho, qee qhov roj av feem ntau txaws rau ntawm ob qho kawg ntawm txhua qhov chaw, thiab cov roj av yog txau rau hauv nruab nrab (feem ntau npog txhua qhov hluav taws kub). Tom qab txhua yam npaj txhij, txhua tus neeg ua haujlwm tau khiav tawm mus rau qhov chaw nyab xeeb 100 meters deb, thiab yuav tsum muaj nyob rau hauv kev coj ua ntej.
