Card room water, solids

Fisher md coworkers (24) have investigated the solids in the card room water supply. Solids content data is given in Table XI. Water samples were taken from the card room at random intervals and 1000 ml S2unples were evaporated to dryness in a crucible on a hot plate. The weight of the dried solids was obtained. The S2unple was ignited at 550 C for 5 hr and ash... 

Recent reports suggest that a significant portion of the dust measured by a vertical elutriator in a card room may be due to solids in humidifier water (23,25,43). Undoubtedly, much of the inorganic matter found in the model card room dusts arises from this source. 

Batra, Fornes eind Hersh (23) recently demonstrated that a significant amount of the material captured by vertical elutria-tors in the model card room at North Carolina State University arises from solids generated by the evaporation of humidifier water. Table IX shows variation in dust concentrations in the card room with and without the contribution of humidifier particulates (23).

Investigations reported in the literature of the inorganic content of cotton plant parts, textile mill dusts, cotton gin dusts, oil mill dusts, and solids from card room humidifier water have been reviewed. 

In almost all cases, rinsing the skin and eyes with copious amounts of water for at least 15 minutes is advised. The only exceptions to this are skin exposure to chemicals that react with water, which are usually solids. (A common example of this is lime, CaO.) In these cases, using a credit card or similar tool to first scrape most of the chemical off the skin is required. For eye exposures and significant skin exposure, immediate transport to an emergency room or a physician is advised.
