Sherpas have threatened to boycott climbing Mount Everest, what can seriously disrupt the remainder of the climbing season.
The move was made after an emergency joint meeting of guides, support staff, expedition leaders and climbers, a press release said.
They held out a seven-day ultimatum to the government of Nepal to address their demands, a press release of Nepal Mountaineering Association said on Monday.
The move came in view of their social security after 13 guides were killed and three went missing in a deadly avalanche on Friday.
The Sherpas have demanded increment of immediate relief and Rs10m compensation to each families of the victims.
They demanded Rs10m for those who cannot rejoin mountaineering and establishment of a memorial park in memory of the dead.
In addition to demands of complete coverage of the treatment expense of those injured, they also wanted a double insurance amount.
The meeting of the Sherpas formulated the demands and forwarded them to the Ministry of Culture, Tourism and Civil Aviation in Nepal.
On Friday, a block of ice tore loose from the mountain and triggered an avalanche that killed at least 13 Sherpas and injured several others.
The worst recorded disaster on Everest was in May 1996 where eight climbers died in a blizzard.
