| SPECIAL RECOMMENDATIONS | 
|---|
| Special Recommendations | Methyl alcohol should not be used in the pressure testing of tanks since failure can occur due to stress-corrosion cracking. · Should have very low interstitial content (i.e. oxygen, hydrogen, nitrogen) to avoid hydrogen embrittlement, etc. This is particularly important when there is a need for welding or heat testing. | 
| Lessons Learned | Welding procedures should always be checked. Argon or helium protection is essential on trailing direction and opposite side |
