posts. This will permit setting the work up tight and 

 its removal without damage to the green concrete. 



Cleaning Out of Forms. All forms must be thor- 

 oughly cleaned out before any concrete is placed. The 

 inspector must be absolutely certain from personal in- 

 spection that all foreign material has been removed 

 from the forms. Particular care must be taken to see 

 that sawdust and shavings are washed out from all 

 places in which they may have collected and that they 

 are removed from the form. In column forms an 

 opening must be left at the bottom for cleaning. This 

 opening must not be closed until concrete is ready. 



Labor. It is desirable that skilled labor be employed 

 on form work and competent foremen are necessary. 

 .One man in each gang must be in charge of it, under 

 the head carpenter or general foreman. 



Removal of Forms and False Work. The forms 

 and false work must be removed with care. IMPACT 

 STRESSES ARE DANGEROUS. EVEN A MOD- 

 ERATE WEIGHT WHEN FALLING CAN CAUSE 

 SERIOUS DAMAGE. All "forms must be eased clown 

 and not allowed to drop. Knocking out of the posts 

 and letting everything fall must not be tolerated under 

 any circumstances. In many cases where reinforced 

 concrete buildings have collapsed, with attendant ser- 

 ious damage and loss of life, the accidents have been 

 caused by the improper removal of the forms and false 

 work. Smashing the forms out is very nearly as dan- 

 gerous as premature removal. 



The men engaged in the removal of thr forms and 

 false work should be very carefully instructed in the 

 danger and the disastrous results caused by careless- 

 ness, which will be liable to subject them to imprison- 

 ment. In the case of an accident they \\ill be held for 

 trial on the charge of criminal negligence. 



The forms should not be removed if there is any 

 load on a panel beside its own weight.
